A North Carolina waitress who served a customer who only asked for two glasses of water has found herself flush with cash.

Alaina Custers customer at Sup Dogs Restaurant in Greenville on Saturday only had a few sips from the waters he ordered.

It must have been good. The man left $10,000 in cash on a table, with a note that said, Thanks for the delicious water, according to the Raleigh News & Observer newspaper.

The supersized tipper wasnt just an ordinary guy with money to burn on water. It was YouTube star Mr. Beast (aka Jimmy Donaldson), who has earned nearly 9 million subscribers through videos featuring extreme acts of generosity, including tipping $10,000 to a pizza delivery driver and $30,000 to random Twitch streamers, according to Newsweek.

He said he wants everyone to know that good things still happen to good people, Sup Dogs owner Brett Oliverio told WRAL-TV. I thought it was pretty cool. I think he wanted to make someones day and wanted to get that wow factor.
