Haircut and a Smoke

I just got my hair cut today, and while I like the guy that cuts my hair, I can't stand that he smokes. And like, right before he cuts my hair so he's all reeking and doesn't wash his hands. So I feel like he's touching my newly-shampoo'd hair, which I have to tip someone for, and running smoky grossness through it. I think I smell smoke now! But what to do, you can't exactly ask the hairdresser to wash his hands, how awkward!
