I once pulled into a city carpark with an attendant at the boom gate. He gestured to a spot and, as he handed me a ticket, told me not to forget to leave my keys with him, so he could "move cars around as required to fit more in".
I made three people behind me reverse out so I could leave. Fuck that.
The valets for the restaurant next to me just use all the metered street parking in front of our building. Imagine paying someone $20 to put $5 into a parking meter 100 feet away.
