A 23-year-old waitress at a popular Langley pub is accused of forging customer receipts to give herself bigger tips, according to documents on file in Island County Superior Court.

Prosecutors charged Jessica R. Engebretson July 3 with four counts of felony forgery. If convicted, she faces two to six months in jail.

The owner of Mo’s Pub and Eatery reported to Langley police on May 25 that she suspected a waitress was altering customer credit card receipts.

Police officer David Marks spoke with Engebretson, and she allegedly admitted to altering 67 receipts over a three-month period, the police report said.

“I altered theses tips to get more money,” Engebretson allegedly said, according to Marks’ report.
