A serving tray system usable by an intended user having a hand to carry objects, the hand having fingers and a thumb, the system comprising: a serving tray, the serving tray including a substantially rigid tray body defining a tray aperture extending therethrough; and a tray mounting element wearable by the intended user, the tray mounting element including a base and a tray mount extending from the base and insertable through the tray aperture to mount the serving tray to the tray mounting element. The serving tray is usable by the intended user to carry the objects thereon when the serving tray is separated from the tray mounting element and held by the hand. The serving tray is mountable to the tray mounting element by inserting the tray mount through the tray aperture to free the hand when the objects have been removed from the serving tray.

1. A serving tray system usable by an intended user having a hand to carry objects, the hand having fingers and a thumb, said system comprising: a serving tray, said serving tray including a substantially rigid tray body defining a tray aperture extending therethrough, said tray body defining a bottom wall, said bottom wall defining a bottom wall peripheral edge, said tray aperture extending through said bottom wall, said aperture including a wider portion and a narrower portion extending therefrom, said narrower portion being closer to said bottom wall peripheral edge than said wider portion, said narrower portion extending circumferentially over a smaller distance than said wider portion; anda tray mounting element wearable by the intended user, said tray mounting element including a base and a tray mount extending from said base and insertable through said tray aperture to mount said serving tray to said tray mounting element, said tray mount including a shaft extending from said base and an enlarged portion extending from said shaft spaced apart from said base, said shaft being configured and sized so as to be received in said narrower portion, said enlarged portion being configured and sized so as to be inserted through said wider portion while being prevented from being inserted through said narrower portion, said shaft having a length that is at least as large as a thickness of said serving tray substantially adjacent said tray aperture;wherein said serving tray is usable by the intended user to carry the objects thereon when said serving tray is separated from said tray mounting element and held by the hand; andsaid serving tray is mountable to said tray mounting element by inserting said tray mount through said tray aperture to free the hand when the objects have been removed from said serving tray. 2. A system as defined in claim 1, wherein said serving tray defines a center of mass, said tray aperture being offset relative to said center of mass. 3. A system as defined in claim 1, wherein said tray aperture is configured and sized for preventing insertion therethrough of any one of the fingers. 4. A system as defined in claim 1, wherein said tray bottom wall is substantially disc-shaped. 5. A system as defined in claim 1, wherein at least part of said tray aperture is between 1 and 5 inches away from said bottom wall peripheral edge. 6. A system as defined in claim 1, wherein said tray aperture extends through said bottom wall in a spaced apart relationship relative to said bottom wall peripheral edge. 7. A system as defined in claim 1, wherein said tray aperture is substantially key-hole shaped. 8. A system as defined in claim 1, wherein said tray mounting element includes a clip extending from said base for clipping said tray mounting element to a piece of clothing or a belt worn by the intended user. 9. A system as defined in claim 1, wherein said tray mounting element includes a belt wearable by the intended user, said base being part of said belt. 10. A system as defined in claim 1, wherein said tray aperture is configured and sized to allow the intended user to position at least one of the fingers in register with at least part of said tray aperture when holding said serving tray exclusively with the hand. 11. A system as defined in claim 1, wherein said tray is provided with indicia substantially adjacent said tray aperture. 12. A system as defined in claim 11, wherein said indicia surround said tray aperture. 13. A system as defined in claim 11, wherein said indicia are luminescent. 14. A system as defined in claim 1, wherein said tray aperture extends through said serving tray. 15. A system as defined in claim 1, wherein said tray body defines an aperture peripheral region surrounding said tray aperture, said serving tray further comprising a deformable patch covering said tray aperture and said aperture peripheral region, said deformable patch defining a patch peripheral region, said deformable patch being secured to said aperture peripheral region in said patch peripheral region. 16. A system as defined in claim 15, wherein said patch is luminescent.
