MURRYSVILLE, Pa. -- A former Murrysville waitress has been busted for taking extra tips.

Police arrested Latisha Fetterman, 27, for changing the amount of tips customers left on their credit cards.

Fetterman, who worked at Rick’s Sport Bar along Route 22, allegedly changed the tip of a birthday party group from $35 to $85. In another case, the customer wrote a $7 tip that was reportedly changed to $37, and police said a $6 tip was changed to $36.

“What we’re finding now is that a lot of thefts and things like this that occur are drug related, and the drug abuser and user out there is desperate and they’re looking for quick cash," said Tom Seefeld of Murrysville Police.

Police encourage customers to check their credit card bills and compare receipts.
