Bad tipping, meet insufferable sanctimony. The two combined into a sorry excuse when a supposed pastor (according to the man himself, who I'm not sure we can trust) left no tip, explaining: "I give God 10%, why should you get 18"
Oooookay. The pastor apparently thinks that anything that involves the concept of a percent is exactly equivalent. I mean, I don't think he's referring to when he asks God for a hamburger and a coke, God delivers it and says that will be $10, and the pastor leaves $11. That would be an analogous scenario.
But no, I believe that the pastor is referring to the practice of many faithful of giving 10% of one's income to the church. The waiter in question is not asking for 18% of the pastor's income. In fact, the waiter wasn't even the one doing the asking! According to the server, in the reddit comments below this post:
“Parties up to eight at my work may tip whatever they’d like, but larger parties receive an automatic gratuity. It’s in the computer, it’s not something I do.”
This is explained on the menu. The waiter said that the pastor was in a party of 20, and that they seemed very pleased with the service. Which makes it all the more gratuitous that the pastor didn't leave ANY tip.
If we ever figure out if this person actually is a pastor and where he preaches, I'd recommend that his congreagation boycott him on account of him being an utter douche. And I hate that word, but it's the most accurate one I can think of.
