Diversion scams can be very nasty since they often divert your attention in very convincing ways.
A few years ago I was in Florence eating lunch outside a nice ristorante. A well dressed couple approached our server and asked her for directions. While I don't understand the entire conversation, it was obvious that they couple was confused and disagreeing with the server. At one point the couple became very hostile shouting at the server in an insulting and accusatory voice. Then, they gave up and left.
A minute after the nasty couple left, a lady at our table found that her purse which had been hanging off the back of her seat was gone. I have to admit is was masterful. We were all totally taken in.
Fool me once, shame on you. Fool me twice, shame on me.
