I don't get how the people here are offended by this. Entitlement? It's so fun to bring something in to just to find out it's gone before you even opened it. Even with a god damn name label. If I bought a carton of milk, I wouldn't mind sharing some, but not the entire thing for one person to make porridge from. At that point you cunts can just buy your own shit.
Duh, a sandwich left in the fridge is the kind of thing no one would ever expect being someone's personal lunch. You're obviously in the wrong to complain about it. Asshole.
