I was living in an apartment complex that didn't have any lines painted to delineate the parking spots, so the assholes would park with 6 feet between the cars. I'd get off of work in the wee hours so I had to park a couple buildings away. When I'd go grocery shopping during the day (and they were at work) I'd return the favor by wasting space, but they'd never get the hint. Also, there was a common entrance to a breezeway that they'd leave the door open to no matter how cold or hot it got outside. When I'd come in at night in the winter, it was freezing in that breezeway, but a couple of hours after I'd shut the door it'd warm up to like 50 degrees F due to heat from the apartment walls. I mentioned it a couple of times when I saw people open the door to come in and just left it open, and they'd be all like "Are you raising your voice to me?" and I'd be like "Yeah, I'd like to get $20 from you and all the others to help pay my light bill!"
