BUR #39230 has been rejected.
create alias empty_plate -> empty_food_container
create alias empty_bowl -> empty_food_container
There's a tag called empty plate which seems to be used for a plate that were either emptied of its serving or is empty because there is no food to be serve. I've noticed that there are several posts under this tag with a bowl instead which fulfils the similar theme mentioned above, which I assumed was tagged because there is no equivalent tag for it.
So, I guess the tag should be repurposed to cover any kind of emptied food container in general. I don't know if an empty cup or other type of container would have its own tag or not or should have its own tag like empty bottle.
