I booked a AirBNB once, and we had already driven an hour, and the owner said they never approved the booking, and "Airbnb messed up" when I called an hour into the drive

Nope, she clearly had forgotten to disable it that night. Then, after I argued, she said "oh just wait 10 mins, I'll see if I can fix it", and wanted me to sit there for 10mins in my car doing nothing.

Another time, its was NYE, it was $400 a night, and the bin there was overflowing at the BBQ, and, we bought ice cream but the freezer was frozen over completely, so it wouldn't fit.
