We have discovered that our newest co-worker is a mooch. It isn't possible to eat anything, even yogurt, without him trying to mooch food for himself. He has a bowl full of food, plus he gets a can of wet food every day, but he still wants what anyone else is eating. Yesterday it was my salad! And it was just vegetables with vinegar and oil!
I'm going to write to Miss Manners and see how she would handle a mooch.
