People who deliberately take forever to pull out of a spot once they see you waiting in a busy parking lot

You can never know for sure, but if you witness people in this situation taking a long time ten times, I'd say at least three of those times they took longer on purpose.

This is one of those things where the counter-argument is more persuasive than it really should be because there's just a lot of low-hanging fruit. You can portray it like the person complaining is just impatient, thinks they can read minds etc. But realistically, it's true.

Sure, you can never know for sure in a given instance, but it's amazing how when you suggest something like this, all of a sudden, no one is a contrarian, no one has a disagreeable personality type, no one does shit just to piss people off, it's allllllll in the mind of the person making the complaint. That's the internet for you, but if we're honest, a significant number of people will do this. Some might just sit there to be a pain, some may just invent shit to do because they're indignant based on the implication that a stranger wants them to "rush". In reality, the person waiting is probably just an everyday person hoping you don't take longer than the usual 15-45 seconds it takes to get ready and drive away.
