I get that parking in the parking lot of a closed business isn't really harming anybody, but that doesn't mean you have the right to park where you want just because you need to.
Most of my personal experience with this type of thing involves people who think that parking in the well marked reserved car share car parking spots for just a few minutes when they need to run a quick errand is acceptable. It isn't. I have to return the car. To its reserved spot. Before my time is up. Otherwise I need to park it (likely) a few blocks away and then someone in the carshare company has to come and move it back. It's costly.
