we had this happen once about 6 years ago. Went to a restaurant. service was HORRIBLE. left the girl a 1 cent tip... figured it sent more of a message than 0 lol only to find out she put the tip in as $50

Called the restaurant. girl was fired. we got our money back. end of story and we've never had it happen again at any restaurant thank goodness

sorry it happened to you. A lesson in why people need to check their bank accounts and statements regularly. A lesson to pay attention. Glad you caught it
