A photo of the receipt, posted to Reddit.com, shows a bill for $34.93 with an automatic 18 percent gratuity (or $6.29) added above a blank space for an additional tip.

"I give God 10%," the diner wrote on the receipt, scratching out the automatic tip. "Why do you get 18?" He then wrote "Pastor" above his signature, and an emphatic "0" where the additional tip would be. (The automatic gratuity, however, had already been added to the total.)

The server added: “They had no problem with my service, and told me I was great. They just didn’t want to pay when the time came.”
