Doesn't parking in same place twice, knowing full well the likely cost to the person they're doing business with, seem unethical? Would you want to do business with someone who carelessly took advantage of you?

I'm not sure I would do that, but I would expect them to fix their service it if it is costing them noticeably.

AFAIK they did not say you shouldn't park underground nor did they explain their various failure modes and how to avoid them.
