A waiter in Kansas took to social media after discovering what looked like a generous $20 tip was not legal tender.

17-year-old Garret Wayman, who works as a waiter at a restaurant in a suburb of Wichita, Kansas, said he was excited on Tuesday to see a $20 bill tucked under a ketchup bottle as a tip.

But on closer inspection, his excitement turned to irritation after he said he realized the tip was a fake.

A customer had really left Wayman a religious pamphlet disguised to look like money that recommended he seek “faith thru Jesus Christ” and start reading the bible.

Here’s a closer look at the fake money:

“I’m 17-years-old, $7,000 in debt because I had to buy myself a car, juggling full-time school, and working seven days a week,” Wayman told Tech Insider, adding that he was excited to see the cash at first because “getting a $20 tip at the restaurant I work at is very, very rare.”

Instead, here’s what Wayman said he found when he unfolded the fake $20:

“Don’t be fooled! There is something you can have more valuable than money,” reads the intro to the pamphlet. On the back is an eight-paragraph argument for why Wayman should buy a bible and become a Christian.

Wayman told Tech Insider the customer didn’t leave a real tip to accompany the proselytizing pamphlet either.

“He just left that,” Wayman said. “I wanted to tell him that I only make $3 an hour and bust my a– at my job to make way less than I deserve, but he was gone by the time I had the chance to.”

Frustrated, Wayman shared pictures of the fake tip on Twitter, where they have been retweeted over 2,000 times.

Though Tech Insider can’t confirm Wayman’s story, tales of servers receiving fake money aren’t new. Previously, a waiter posted a picture of a tip he said he received to Reddit that turned out to be fake $10 with similar religious messages on the back. Another waitress also posted a picture of the same fake money on Reddit.

Wayman meanwhile remains understandably frustrated: “To get my hopes up like that … is just flat out mean.”
