It's a viral challenge that those in the hospitality sector would like to see more of.
A waitress cleaning tables at a restaurant in Massachusetts was surprised to pick up a hefty tip.
Jennifer Navaria was thrilled to read the bottom line of her last customer's receipt, reported FOX News. A US$5000 ($7700) gratuity was included on a bill for the $150 meal at the Seaglass Restaurant.
Navaria initially was delighted to pick up what she thought was a generous $50 tip.
"But then when I went to the bottom (with the total), it was four digits, then a decimal point. So that's when I knew it was not $50," she told local TV channel Fox News 23.
"I was shaking. And it was, like, really unbelievable," she said.
In the States it is customary to tip around 15 per cent. 20 if one is feeling generous, but 3000% is unheard of.
