LOOK: 'Very Generous Customer' Leaves $16,000 Tip At New Hampshire Restaurant

LONDONDERRY, N.H. (CBS) -- A "very generous customer" left a tip of $16,000 on a bill that was less than $40 at a New Hampshire restaurant. It happened June 12 at the Stumble Inn Bar & Grill in Londonderry.

Owner Michael Zarella posted a photo of the receipt to Facebook. It shows that the customer had two chili dogs, a coke, pickle chips, a beer and a tequila - and left the staff $16,000 on a Visa debit card.

"Stumble Inn had a very generous customer," Zarella wrote. "We thank you for your generosity."

The bar is keeping the identity of the big tipper anonymous.
