Waitress got the Shock of her Life As Customer Tips Her $10,000 After Ordering Water.

A waitress was stunned to receive a massive cash tip of $10,000 given to her by a big-hearted customer. Alaina Custer was working a shift at Sup Dogs in Greenville, USA on Sunday when she noticed a man walk in and sit down at a table.

The East Carolina University student said he ordered two glasses of water before getting up and leaving behind a large stack of bills.

Beside the money was a note that said “thanks for the delicious water,” according to Sup Dogs owner Brett Oliverio.

“I literally didn’t think it was real. I picked it up and it was a giant stack of hundreds, I was shaking and just kept asking, ‘What is this?’ I thought someone was playing a joke on me,” she told The News & Observer .

Custer says there were two other men at a nearby table laughing at her and recording her reaction.

It later transpired the mystery benefactor was a YouTube personality known as Mr. Beast.

“They just told me about their YouTube channel and how they were going around blessing servers’ days,” Custer said.

Custer unselfishly shared her tip with the rest of her co-workers, taking just $800 of the large donation.

Mr. Beast, who has over 8.8 million subscribers on his channel, came back to the restaurant and “hugged them all”, according to Custer.

“I was so blessed to have that money. We got to all split it up, which will help a lot of people,” she said.

The sum is comfortably the biggest ever tip received at the restaurant, which is a favourite of students at nearby East Carolina University.
