A hand-held plate for holding a beverage container and food includes flexible flaps which frictionally engage the outer peripheral surface of a beverage container to maintain the beverage container in stable condition relative to the plate. o the opened position; a check valve member for preventing the actuation fluid from deactuating an actuated packer element; and a secondary opening device secured to the cementer housing in at least one of the one or more cementing ports for opening at least one of the one or more cementing ports in response to a selected cementing port opening fluid pressure in the cementer housing when the packer element has been actuated to a set position. 4. The stage cementer assembly as defined in claim 3, further comprising: a pressure equalizing valve in the cementer housing for equalizing a fluid pressure in an opening sleeve annulus with a wellbore fluid pressure in the wellbore annulus while running the stage cementer into the wellbore. 5. The stage cementer assembly as defined in claim 3, wherein the cementer housing comprises: an upper body having lower threads thereon; and a lower body having upper threads thereon for mating engagement with the lower threads on the upper body, for securing the opening sleeve assembly within an interior portion of the cementer housing. 6. The stage cementer assembly as defined in claim 1, further comprising: an opening shear member of a first selected shear strength for disengagingly securing the opening sleeve assembly to the cementer housing, and for shearing when the opening sleeve assembly moves from the closed position to the opened position. 7. The stage cementer assembly as defined in claim 6, further comprising: a closing shear member of a second selected shear strength for disengagingly securing the closing sleeve assembly to the cementer housing and for shearing when the closing sleeve assembly moves from the opened position to the closed position. 8. The stage cementer assembly as defined in claim 1, wherein the opening sleeve seat of the cementer housing further comprises: a substantially frustoconical wedge portion formed at an angle with respect to the cementer axis of up to 70 degrees. 9. The stage cementer assembly as defined in claim 8, wherein a lower portion of the drillable opening sleeve portion includes an engagement surface for engaging the substantially frustoconical wedge portion to prevent rotation of the drillable opening sleeve portion during drill-out. 10. The stage cementer assembly as defined in claim 1, wherein both the drillable opening sleeve portion and the drillable closing sleeve portion are formed from a composite material. 11. The stage cementer assembly as defined in claim 1, further comprising: one or more first splined connections for securing at least a portion of the opening sleeve assembly to the cementer housing; and one or more second splined connections for securing the opening sleeve assembly to the closing sleeve assembly to prevent rotation of the drillable closing sleeve portion of the drillable closing sleeve and drillable portion of the opening sleeve assembly during drill-out. 12. The stage cementer assembly as defined in claim 1, wherein the drillable closing sleeve portion is rotatably secured to the opening sleeve assembly during drill-out of the drillable closing sleeve portion. 13. The stage cementer assembly as defined in claim 1, wherein the cementer housing has a maximum outer diameter of not more than five inches. 14. The stage cementer assembly as defined in claim 1, further comprising: a locking member retained on the closing sleeve assembly; and a lock member positioned within the cementer housing for engagement with the locking member on the closing sleeve assembly to lock the closing sleeve assembly in the closed position. 15. The stage cementer assembly as defined in claim 14, wherein the lock member is positioned between an upper seal on the closing sleeve assembly and a lower seal on the closing sleeve assembly when the closing sleeve assembly is in the closed position. 16. A method of operating a stage cementer, comprising: releasably securing an opening sleeve assembly within a ce
