Customer: Do you know there's only one thing worse than a male chauvinist pig? Barber: And what's that? Customer: A woman who won't do what she's told!

A customer was sniffling while I was cutting his hair. I brought him a box of tissues and left them beside him. The customer in the next chair having his hair done noticed and was watching. Barber: I see you have a touch of a cold there. Customer 1: Yes, I was out for a few drinks last night, and I woke up sneezing this morning. Customer 2 (in the next chair): Well, that's what you get for drinking out of a damp glass!

and many more!
