I've got two, that are related.
Background - my husband has had 24 strokes in the last 7 years, and is in end-stage renal failure. Since I cannot leave him alone, we have had to take the distasteful step of applying for, and receiving, food stamps. So, here goes:
Pet Peeve #1. People who think they are better than me when they see that food stamp card in my hand.
and
Pet Peeve #2. Seeing people in grocery store lines, with a basket of food, cartons of cigarettes and 5 12-packs of beer. If you have money for cigarettes and beer, you should be getting your own groceries.
I know, taken together, they are sort of hypocritical.
