How big of a tipper are you? Most people go with an average of 20 percent. Rhode Island waitress Kristen Ruggiero, who makes about $100 on a good night says she was stunned when she saw the tip for a $42 tab at Uncle Tony's restaurant in Cranston, Rhode Island.

How much did they give her?

A Rhode Island couple gave their favorite waitress a reward for her years of great service with a tip of 1,091 percent.

When she picked up the bill folder she asked the couple if they needed change. 'No,' they said. Everything was all set.

Inside the folder Ruggiero found five $100 bills.  It was money earned for many years of great service.
