18-year-old gym bros spend $120 on groceries, force celiac roommate to pay the same amount: 'It's not our issue you choose not to eat'

Figuring out how to share food with your roommates can be a tough gig. There's no one way to do it. The easiest way seems to be that everyone buys their own groceries, and you're not allowed to touch each other's without asking. This is all fine and good until there are 3 sacks of flour in the pantry, 3 gallons of milk in the fridge, and 3 cartons of eggs all spoiling at the same rate, and taking us unnecessary space. 

Plus, it can end up being cheaper for everyone if you share groceries. But not everyone eats the same thing or the same amount, so how do you split the cost evenly? It's no wonder that conflict tends to arise from these types of decisions. That's what happened to one roomie group whose eating habits had a major clash.
