The waitstaff at the Stumble Inn Bar & Grill in New Hampshire got the surprise of a lifetime when a customer left them a $16,000 tip. The restaurant owner, Mike Zarella, said "I thought it was a mistake. Typo". But sure enough it wasn't, it was real. The customer purchased just a few things with a total bill around $37. One of the waitresses said that he assured them it was real and that he just wanted to do something nice because they work really hard.
