(Gawker) - Unhappy with having to pay a restaurant's auto-gratuity of 18% for parties of eight or more, a pissed-off pastor used his receipt to express his indignation.

"I give God 10% — why do you get 18?," the man wrote above the autograt line before crossing out the pre-printed tip and signing the receipt "pastor."

The St. Louis-area server who posted a pic of the receipt on Reddit said the pastor was dining with a party of 20, and asked to have the $200+ bill broken up into smaller increments in a failed attempt to avoid paying the 18% tip.

"They had no problem with my service, and told me I was great," the server said. "They just didn't want to pay when the time came."

Redditors have been trying to track down the less-than-charitable Christian, but have so far been unable to identify the culprit.

At least one pastor was forced to issue a response denying responsibility, and the server herself has asked fellow Redditors to stop posting personal information of random people "who don't deserve a Reddit mob banging down their Internet door."
