In my limited B&M experience, I've had a few situations where arrogant dealers really rubbed me the wrong way.
But a part of me really enjoys public confrontation.
I don't go out looking for trouble, I'm not like that at all. But I get a kick out of putting someone in their place when the situation arises.
I've done it to 1 dealer, a couple waiters/waitresses, a bartender or two, etc. I really get nasty with credit card people, but that's on the phone. Have you ever tried to cancel a credit card? They WILL NOT let you off the fucking phone!!!!
Anyway, I just like the surprised look on their face when I tell them where to put it without mincing words. People just aren't used to others being really direct and blunt without reservation.
