I have had pockets picked in:

Aswan (walking up the Corniche at night being pestered by a man claiming to sell papyrus). They took a few Euro and a rather nice red leather wallet from Marrakech that was worth nothing

Athens - Metro just after Victoria station - surrounded by guys who made the carriage feel crowded - on getting off I checked for my wallet and found it was missing, the guy who had it handed it to me and asked whether it was mine. Baastard. I was on my guard thanks to Lonely Planet but had a stupid amount of money and cards in the wallet. Lucky escape.

London - Department for Education staff bar one night. Took my cash card but replaced the rest of the cards. Made £3000 over the weekend but all refunded by my bank less £8 service charge for a new card.
