The place where I get my haircut gives me a glass of bourbon while I'm getting a trim. It's the best idea ever. Not just because it turns what is otherwise a rather dull experience for me into something enjoyable, but because I always tell them I like my hair after they're done. Then a couple hours later after a shower and a cup of coffee, I realize that they left it way too long. Instead of going back into get it fixed, I just live with my mullet for a month and schedule another haircut way earlier than I normally would have. It's good business for them.
