So have I. It occurred in a packed baht bus in Pattaya. Pretty soon it was just me, the LB and a farang guy with a Thai chick sitting across from me. The baht bus took a turn and the LB slid across the bench right up against me and I immediately saw he/she was grabbing for my wallet. Grabbed his hand and slammed him up against the wall of the compartment, he looked shocked and pressed the buzzer and jumped off the bus. The couple across from me looked shocked and the girl said I should go back to hotel and change clothes to look different in case anybody would look for me. Took her advice and did, lol.
