The problem is, Seattle’s $15/hr minimum wage hasn’t phased in yet, and the bartender isn’t making $15/hr. (Nor did the customer pay “for that increase” at today’s prices.) But don’t expect people who wear their rightwing politics on their sleeve to bother with such details. Don’t expect them to have any manners, either. And, frankly, I suspect this guy doesn’t tip in places where the minimum wage is $7.25/hr, either. I think he’s just a cheapskate.
