I may have snapped gloves before when I put them, I think I haven't done it since my second year when a co-worker (joking with me) said "don't put hose on behind me". Since that time, I have made a concious effort to not do that at work. I think that many of the folks that do it, have seen it done that way on TV and such, and do so subconciously in many cases. There are sometimes where I think that knuckleheads are doing it to make a point or intimidate (which is wrong on evey level) someone. I have seen it happen many times where TSOs are not really paying attention to the fact that they snapped them (which reinforces the subconcious angle). Just my 2 cents.
