The owner of the restaurant was tipped off when a customer called to say his bill was too high. The 77-year-old Bellevue resident spent $27 at the restaurant but was billed $37. That's when the owner said he went through all of the server's recent receipts and told KIRO-7 it was easy to see what she'd been doing. He said a customer might have a bill for $12 with a $2 tip, instead the server would add a "1" to the tip, making it $12.
