<human>: I found a wallet with just over $4,000 dollars in it in a car park in a dogey mall where I work. It had nothing in it except a pension card so I took it into the police and left my phone number but checked the guy out on facebook anyway and it turned out he was a pretty obvious drug dealer. Now, I didn't expect a reward but a thanks I did expect and the police ended up calling me the next day where I work to say he picked it up and they told him he could go and see me at the ice-cream shop where I work in that mall. But no, nothing. Anyway the punch of the story is that the day after I got my pay out and went to get some things from the same mall. Lost my wallet buy accidentally missing my handbag or shopping bag or IDK and of course it was brought back to me at work by the cleaner who found it in the bin. Empty.

Can you give me the gist of the text in a nutshell?
