The answers to this thread are simple. There are assholes everywhere. No matter where you are. Nobody likes the I'm too cool for you Tattooer, Bartender, Sales Clerk, whatever. We also don't like the whiny customer, guy who waves his money in your face like he is buying you type, or stalkers, or the never satisfied customer. There is etiquette for any business out there. If you don't act accordingly you will either: Lose customers, Not get served, be asked to leave, or in extreme cases, Beat the Fuck up. You are not the only Tattooer in town, and You are not the only customer in the shop. It's really easy. And if somebody doesn't treat you right....don't come back. That's like the battered wife who stays with her husband. "He mistreats me but I keep going back, whimper, whimper."
Ok I'm done. Get it? Got it? Good.
