Few years ago I was selling my F150, after a whole bunch of lowballin tire kickers I had some mother/son combo asking to see it. They had me drive out to their place, then had the neighbour "mechanic" look at it and test drive it. They came back complaining about random garbage and said they would buy it IF I safetied it + fixed the BS complaints.
I told them, sure Ill safety it if you give me a deposit, that way if you dont take it at least Im not out of pocket. They out right refused to give me a deposit, I said ok, I'll safety it but its first come first serve then(the mom tried to tell me it would be rude if I sold it to someone else, but I told her cash talks and she hadnt given me any).
About a week later I get the truck fixed up and Im getting calls about my truck all day long (updated ad to say it was ready to roll, safety + etest). Called the woman back to say it was ready, she got all excited and said to me that should would have her "mechanic" do a final inspection before handing over the money(and all i could think of was that this could be her easy way to back out of the deal). Then soon as I hang up, some guy called, asked a few questions about the truck and said he was on his way with cash in hand. Called the woman an hour later to tell her the truck was sold.
I was literally laughing about it all the way to the bank!
