Peanuts on Your Table Scam
How the scam works:
You enjoy an evening out with your friends on a patio. The trip has been good, and the drinks are pouring. Amongst waitresses serving around, a young girl might stop by your table and drop off a small paper cone with ten roasted peanuts and a napkin. The she leaves.
As she doesn't show up anymore, you and your buddies start eating the peanuts. Suddenly, she shows up asking for $4, 5 or 6 dollars or EURO (or the equivalent currency in that country). As you thought was complimentary she starts creating a scene, saying she is hard working girl, half deaf, etc, while embarassing you in front of the other customers. You might hand her the money just to get away.
