Only a Jewish person could do this

I just had a guest go off on me because his 20 dollar gratuity was taxed and he wanted me to give him a refund for the dollar and change.

These people screwing with you most likely worked in customer service at one time. You work shit jobs like this so you learn how to get what you want. Unless you're a giant pussy, then you should remain put.

Of course, what you "want" is the big question, such as the fellow at 2's gas station. You won't get anywhere going to a Best Buy demanding a spaceship to take you to Africa.
