I think that item that You hold in hands because for example Your invetory is full should not be dropped after use. Like when u pick up some tuna and u will eat 1 piece it should not land on ground right after You end the process. It should happen when either can i empty or player really wanna drop it. Also i think that when u will press eat on any item that is on groud character should grab it insantly. Right now it like saves Your choice because when u will press eat on item that is on ground and then u will take it to hands he will start to eat it right after.
