I see lots of terrible parking in the course of my job, mostly by entitled people who are too lazy to walk more than three feet to the door, so the block the door to the shop. But we don't have gas pumps.
I think the worst one I've seen with gas pumps, and it was so much entitled as it was stupid, was this one guy at Sam's. He had one of those push-button start cars (don't get me started on how dumb those are). Anyway, he dropped his girlfriend off over at the store across the plaza and went to get gas. He shut the car off, pumped his gas, then remembered the key was in her purse.
