Did anyone ever tried to steal your pocket wallet? How?

While being in Barcelona Metro 3 mens tried to steal my pocket wallet. I was entering the train and one of them jumped in front of me and suddenly turned around and actually blocked me. So he probably thoght I will remove my hand from my pocket and move him, while his two assistants from the back pickpocket me. I didn’t !

One of the passengers shouted loud “thief thief” in Spanish. Since I did not understand the language I did not realize at first what he was shouting, then all the three ran fast out of train.

The attempt failed, but if I move my hand, I guess they were successful. They are smart, but I am smarter. This incident is so unpleasant. Unfortunately, all the other passengers on the train were indifferent and did not speak. Since that I was a little bit scared using again the great Metro of Barcelona. Be careful!

Has this happened to you? How? Did they succeed?
