As soon as break starts all dupes need to go to the bathroom and eat
Unless there is an outhouse/lavatory for every dupe, some dupes need to wait to use the bathroom and they go to the mess hall to eat
Once an outhouse/lavatory is available eating dupes will DROP their food to the floor to use the bathroom
drooped food won't get picked up till morning allowing it to spoil
Steps to Reproduce
have more dupes than outhouses/lavatories, watch them eat during break time
