"a $10 tip on an $800 bill"
I've said before, I'm not a fan of "tip inflation" - rising from 10 to 15 and now 20%.
But this is ridiculous.
A guy who makes close to $100,000,000.00 a year leaves a $10 tip (1.25%) to the working class wait staff?
That isn't frugal or mustachian, that's just being an a-hole.
