10. Dropped wallet scam
This scam is very popular in Eastern Europe among con artists preying on tourists. A person drops an empty wallet and unassuming tourist picks it up with an intention to give it back. The person accuses the tourist of taking the money out of the wallet and threatens to call the police. If the scam is taking place in a shadier part of a city, instead of the police, two or three large individuals will show up and start asking the poor tourist to give the “stolen” money back. You can guess how the story ends.
