This is just me but, who cares? So what, the cashier thinks you're a security guard, maybe the captain of a cruise ship. Odds are, you will never see that person again in your life, and if you see them regularly, they probably know that you're an airline pilot (cause pilot nature says we'd tell them within 2 minutes). I do agree, if you're going to wear it, dont look like a dumb@ss doing it, cause you just make yourself look like even more of an idiot. My point: do we really need (another) a thread about this?

*Cue discussion about backpacks, ipods, and earbuds*

BTW, is it acceptable to go to the laundromat in uniform, strip down, throw it in wash/dryer, take it out, put it back on, and walk out?
