The only time I didn't mind seeing someone eat in the store before paying was a type 1 diabetic whose blood sugar had crashed.  He was desperately scrambling to drink some orange juice before he passed out.  He paid for the purchase and apologized for opening food inside the store before getting to the register.  He even tried to take the second bottle of juice outside before drinking it, but he was shaking so hard we were afraid to let him leave the store.  We had him sit down and rest until we knew for sure he was okay. Fat fucks need to be beaten senseless until they can understand this one simple concept.  This is what low blood sugar actually does to a person.  It doesn't mean going for three seconds without food.  Medical emergencies are not the same as gluttony.
