He may have thought that he had just encountered the rudest customers, that is until he got to work the next day.

A pizza delivery driver was not happy after he delivered a pizza to a couple who tipped him only 33 cents! The total bill was $22.67, and the couple gave him $23.00 and told him to "kepp the change." Wow, big spenders. But the next day, he arrived at work to a BIG surprise!

When the couple realized their math mistake, they went to the pizza place and left a $20.00 tip and a note that read... "We would like to apologize for our impaired math skills and thank you for the work you do! We appreciate it immensely! -Tom and Jenn"
