Yep. When I was in service, the most abusive set of customers I ever had was....a table of super-showy "Christians" (ostentatiously saying prayers, talking about their church, blah blah blah - they were also the meanest, most demeaning people I ever had to deal with in my life). I didn't say shit to them. After about the 4th time they berated the shit out of me, I went back in the kitchen, and told the manager "table 5 is yours, I'm not going back over there." And that was that.
He personally finished out their service, and said "yeah, they were awful, even to me. Here's the tip, you earned it." I told him nope, I don't want anything to do with them, including their money.
See, it's easy not to be a confrontational piece of shit. Just....don't be a piece of shit.
Oh, and fuck this fucker.
"All these people who say I'm racist are totally making me be a racist!"
"Also, I don't want to beat my wife. Why does she keep provoking me by burning my pancakes? Stop making me hit you, Linda!"
HOWEVER, I will say that it's okay to hate people for certain very good reasons. For example, I think that he should be dragged behind a team of Clydesdales until his skin peels off for wearing that stupid-ass visor. There are few looks on earth that scream "dear God I need an ass-kicking" more than the white man visor look.
