I worked at a gas station where several times a week I would find a full trash bags of garbage in the trash can at the pumps. The gas station was in a small unincorporated town with no garbage pick up and somebody was using our trash cans to dispose their home trash. All the other trash would overflow on top of the bags and it was a big pain in the ass. When I caught the lady who was doing it and asked her to please not use our trash cans as her personal dump, she flipped out about how many years she'd been coming there and how much money she spent on gas, and how she's not spending another dime there. I told her we don't make shit on gas, and never saw her actually in the store buying things, so her money won't be missed.
