I have a few times. Several times at the mall, I had what I could only term as a gang of young girls come up to me oohing and aahing over a bag. I felt really uncomfortable and as I had heard of some robberies in the parking lot and one actually in a rest room where someone was followed and her purse stolen (she had said, "Oh, yes, of course it's real!"), I said - "No way, it's a really good fake, don't you think? I would never pay those kinds of prices!" It was a situation where I felt I was potentially making myself a target by admitting my bag was real.
