In today's informed society, I really don't understand how anyone thinks they can get away with something like this... but then again these guys are mostly idiots. I've had a guy try to talk me out of money ("My car broke down in the parking lot here, I left my wallet at home and need a hundred bucks for a cab, can you spare anything? [insert military service story to guilt me]") while telling me his rank in the Army was Commander while I am WEARING a unit T-shirt hinting that I'm military... It's bad enough they're dumb enough to try it, but worse when they go for people who obviously know better...
