wrist watch snatching

Its 2000 or 2001 year, i was just sitting in front of my friend's home near Kashmir road, Karachi, Pakistan. Two person came on the bike and one of them addressed us and asked that where Mr. xyz person lived in the near place where we were sitting. I stood up and tried to listen him clearly suddendly he said me that he wanted my wallet, and other goods I had with me at that time. It was an evening. Then, he asked for my wrist watch and I handed over to him. The other person was on the bike. They showed that they had any pistol but they did not show. Then, they said my friend the same. But, he said he did not have any thing in hand at that time. Then they both sit on bike and said us not to follow them. After that day, whenver I use to go to the home by foot I feel the same thing and any in coming bike or car makes me fear. Now a days, its a routine that people on bike or car, ask for some place or person when you get close to them they showed you the pistol or any weapon and ask for your wallet, mobile phones etc. Its my request for those people, please do not resist with the snatcher, becuase you are more valuable then those good in eyes of your mother, father, sister, brother, children, spouse. Its a sincere message from my side. May be, a few person have other opionion than me.
