• a bowl or plate configured to carry a foodstuff;
• a receptacle coupled to the bowl or plate, wherein the receptacle includes:
• a compartment for receiving an object, and access to the compartment in the receptacle is obstructed by a bottom wall of the bowl or plate, and
• a clear window disposed to display the object in the compartment as an incentive to clear the foodstuff from the bowl or plate;
• a latch coupled to either the bowl, the plate or to the receptacle;
• and
• a detent in either the bowl, the plate, or the receptacle, configured to receive the latch,
• a magnetic lock coupled to the bowl or plate and coupled to the receptacle, wherein:
• in the event the magnetic lock is opened, the latch releases from the detent, and
• access to the compartment in the receptacle is provided in the event the magnetic lock is opened.

A system, comprising:

• a first receptacle;
• a second receptacle coupled to the first receptacle, wherein the second receptacle includes a compartment for receiving an object, and access to the compartment in the second receptacle is obstructed by a wall of the first receptacle;
• a magnetic lock coupled to the first receptacle and to the second receptacle, wherein:
• the magnetic lock includes a first magnet and a second magnet disposed in magnetic attraction to the first magnet, and
• access to the compartment in the second receptacle is provided in the event the magnetic lock is opened;
• and
• a magnet key including a third magnet, wherein in the event the magnet key is placed proximate the magnetic lock, the third magnet displaces the first magnet from the magnetic attraction to the second magnet to open the magnetic lock.
