Corporate joints, they figure if they don't waste the food people would be motivated to see food is wasted that could be used. And it would prevent managers from slipping in expired food they aren't supposed to use anyway because they are under pressure to lower waste costs. So they throw out food rather than let anyone have it.

Plus if you feed someone, they aren't going to be buying food. It's completely just a theoretical self serving philosophy, that's why I refuse to work for corporate joints like that.
