Tourists stealing from tourists. It's been known to happen.
Let me relate a story that I may have told before. I'm not sure; but I like to tell it anyway.
My son is a restaurant manager here in Niagara Falls Canada. We get 13 million visitors in a good year and it takes all kinds.
A table of 4 (two couples) were leaving the restaurant and the server was told the money was on the table. Well, it wasn't.
The guy who left the money on the table with the bill swore up and down he paid the tab and left a generous tip and then began accusing the staff of ripping him off.
My son said hold on a minute and checked the security video. Guess who stole the money! The couple they were travelling with scooped it.
