The invention claimed is: 1. Apparatus comprising a bill dispenser having a dispensing location at which bills are to be delivered to users, a bill storage chamber having a withdrawal end from which bills are to be withdrawn, a skew detector positioned at the withdrawal end of the bill storage chamber to detect skew in bills withdrawn from the chamber, a double detect mechanism positioned downstream of the skew detector to detect double bills that have been withdrawn from the chamber, after the bills have been subjected to skew detection, and circuitry to divert a skewed bill from being dispensed at the dispensing location. 2. The apparatus of claim 1 in which the skew detector includes optical sensors arranged along a direction at an angle to the direction of the paper path. 3. The apparatus of claim 2 in which the skew detector includes timers configured to determine the timing of the passage of currency along the path relative to the optical sensors. 4. The apparatus of claim 1 in which the skew detector also detects a length of the currency. 5. The apparatus of claim 1 in which the double detect mechanism comprises a free end of an elongated finger configured to be moved, when the bill is driven through the paper path, by a distance that corresponds to a thickness of the bill, and a pair of inductively coupled elements that are configured to be moved relative to one another by motion of the elongated finger to detect the distance that corresponds to the thickness of the bill. 6. The apparatus of claim 1 in which the skew detector is located to receive bills from the end of the bill storage chamber. 7. A method comprising feeding a bill from a withdrawal end of a bill storage chamber and along a paper path toward a dispensing location at which bills are to be delivered to users, optically detecting a skew condition of the bill at a skew sensing location at the withdrawal end of the bill storage chamber, after the skew condition has been detected, detecting the presence of a double bill at a location between the skew sensing location and the dispensing location, and diverting a skewed bill from being dispensed at the dispensing location. 8. The method of claim 7 in which the bill is fed from the end of the bill storage chamber to the skew sensing location. 9. The method of claim 7 in which a decision to reject a skewed bill is made after the detecting of the skew condition and without regard to detecting whether the bill comprises a double bill. 10. The method of claim 7 in which detecting the presence of a double bill comprises pushing a free end of an elongated finger by an amount that corresponds to the thickness of the bill, and by electromagnetic coupling determining the amount by which the free end is pushed. 11. The method of claim 10 in which the pushing of the free end causes rotation of the finger about an axis. 12. The method of claim 11 in which the amount by which the free end is pushed is determined by relative rotation of two inductively coupled elements. 13. Apparatus comprising a bill dispenser having a dispensing location at which bills are to be delivered to users, a bill storage chamber having a withdrawal end from which bills are to be withdrawn, a skew detector at the end of the bill storage chamber to detect skew in bills withdrawn from the chamber, a double detect mechanism positioned downstream of the skew detector to detect double bills that have been withdrawn from the chamber, after the bills have been subjected to skew detection, and the double detect mechanism comprising a free end of an elongated finger configured to be moved by a distance that corresponds to a thickness of the bill, and a pair of inductively coupled elements that are configured to be moved relative to one another by motion of the elongated finger to detect the distance that corresponds to the thickness of the bill. 14. The apparatus of claim 13, in which the skew detector includes optical sensors arranged along a direction at an angle to the direction of the paper path. 15. The apparatus of claim 14, in which the skew detector includes timers configured to determine the timing of the passage of bills along the path relative to the optical sensors. 16. The apparatus of claim 13, in which the skew detector also detects a length of the bill. 17. Apparatus comprising a bill dispenser having a dispensing location at which bills are to be delivered to users, a bill storage chamber having a withdrawal end from which bills are to be withdrawn, a skew detector at the end of the bill storage chamber to detect skew in bills withdrawn from the chamber, a double detect mechanism positioned downstream of the skew detector to detect double bills that have been withdrawn from the chamber, after the bills have been subjected to skew detection, and the double detect mechanism comprising a pair of inductively coupled elements that are configured to be moved relative to one another to detect the distance that corresponds to the thickness of the bill. 18. The apparatus of claim 17, in which the skew detector includes optical sensors arranged along a direction at an angle to the direction of the paper path. 19. The apparatus of claim 18, in which the skew detector includes timers configured to determine the timing of the passage of bills along the path relative to the optical sensors. 20. The apparatus of claim 17, in which the skew detector also detects a length of the bill. 21. A method comprising feeding a bill from a withdrawal end of a bill storage chamber and along a paper path toward a dispensing location at which bills are to be delivered to users, optically detecting a skew condition of the bill at a skew sensing location at the end of the bill storage chamber, detecting the presence of a double bill at a double detecting location along the path, and diverting a skewed bill from being dispensed at the dispensing location, in which a decision to reject a skewed bill is made after the detecting of the skew condition and without regard to detecting whether the bill comprises a double bill. 22. The method of claim 21, in which the bill is fed from a bill storage chamber to the skew sensing location. 23. A method comprising feeding a bill from a withdrawal end of a bill storage chamber and along a paper path toward a dispensing location at which bills are to be delivered to users, optically detecting a skew condition of the bill at a skew sensing location at the end of the bill storage chamber, detecting the presence of a double bill at a double detecting location along the path, the double detecting location being between the skew sensing location and the dispensing location, the detecting the presence of a double bill comprising pushing a free end of an elongated finger by an amount that corresponds to the thickness of the currency, and by electromagnetic coupling determining the amount of by which the free end is pushed. 24. The method of claim 23, in which the bill is fed from a bill storage chamber to the skew sensing location. 25. A bill dispenser comprising a chamber to hold a stack of bills, the chamber defining a location on one side of the stack of bills from which the bills are withdrawn, then passed along a paper path and dispensed through a wall to a customer standing on the other side of the wall from the bill dispenser, a skew detector at the location where the bills are withdrawn from the stack, and a double detect mechanism positioned downstream of the skew detector to detect double bills that have been withdrawn from the chamber, after the bills have been subjected to skew detection. 26. The bill dispenser of claim 25 in which the bills lie essentially vertically in the stack and a withdrawal mechanism is configured to draw each bill downward from the stack at the withdrawal location and immediately to reverse its direction to cause it to move upward toward the dispensing location. 27. The bill dispenser of claim 25 in which the paper path is straight and vertical. 28. The bill dispenser of claim 25 in which the chamber that holds the bill stack comprises a removable cassette that is to be withdrawn from the dispenser in a direction away from the paper path. 29. The bill dispenser of claim 25 in which the chamber comprises a removable cassette and the paper path lies between the chamber holding the stack of bills and the wall at which the customer will stand so that the paper path prevents the bill dispenser from being removed from the side of the bill dispenser that faces the customer. 30. The bill dispenser of claim 25 in which the location where the bills are withdrawn from the stack is next to the inside of the wall and offset below the location at which the bills are dispensed through the wall. 31. A bill dispenser comprising a removable bill cassette, a vertical paper path to carry bills directly from a lower location at which the bills are dispensed from the front of the bill cassette to an upper location at which the bills are dispensed to a customer through a vertical wall, the bill cassette being held behind the paper path and above the lower location of the vertical paper path, a skew detector positioned at the lower location of the bill cassette to detect skew in bills withdrawn from the chamber, and a double detect mechanism positioned downstream of the skew detector to detect double bills that have been withdrawn from the bill cassette, after the bills have been subjected to skew detection.
