I won't begin to stick up for shady characters or anyone with a good poker face, but sadly I have an eye disease that requires me to wear dark prescription glasses outdoors always and inside brightly lit stores, supermarkets etc. I've heard mumblings of crap like "what are you a F#$(&^g movie star or something" to "why dont you take off your shades so you can see what you're doing". The sad thing is, is that I can't see what I'm doing without them. I even have to where them while watching TV during the day. I would much rather fit into the crowd rather have someone ask me if I'm selling pencils.
