I just quit after calling the police. Dude said they were too hard to scratch off and wanted his money back. Was dressed to the nines (as was his date), in a seedy movie rental store, trying to return lottery tickets by amicably dropping threats of coming behind the register.

I sure hope his date was impressed. Nobody else was.

Edit: also, this was about 20 years ago, so may very well have been a scam attempt.
