Put Time Constraints on Us. "I have to be at work in an hour, can you get my tattoo done by then?" Large pet peeve right there.
We create art -- don't tell us when it has to be done. And, if we charge you for one hour of work, but we decide to get creative and tattoo you for two hours at no extra cost, do you really want to stop us from doing that?
Please don't assume you know how long it takes for a tattoo to be done, either. I had a guy tell me the other day he wanted the entire Lord's Prayer on his arm, and that shouldn't take me a full hour, right?
Oh, you're right. It will take me over an hour. So please, have your day open when you schedule your tattoo appointment.
