@Brian2036- Yes, that was very early in my hosting career and I was much MUCH kinder than I should have been. I found out later they were a homeless couple, migrating around the area living in AirBNBs and were pretty spaced out most of the time. They had thought that they could arrive anytime they wanted on check-in day and had showed up at 10AM. The guy then attempted to use a rock on a window which was cracked, trying to force it open somehow while the woman called me and said they couldn't get into the house.
We let them in at noon and charged them for emergency early check-in, so at least made some extra money. There were no real issues in the house except they had a habit of, whenever they wanted to use the kitchen, they would just stop the oven or the microwave if someone else was using it, pull the other person's food out, and use it themselves then just walk away. The thing I remember the most, though, was that they were wary the police were looking for them. They apparently had a car with plates from another car (an arrestable offense) and had *thousands* of dollars in fines from red light and speed camera tickets and at least one bench warrant for not showing up on a moving violation charge to court.
They left at the end of the stay without incident and I actually didn't say anything about the 10AM break-in attempt since they had later paid extra. Today, however, older and wiser host I would definitely have slammed them in the review.
