A group of restaurant workers was left shocked and amazed when a regular diner left them a hefty tip, then disappeared before they could say thank you.

The employees at Eggs Up Grill in South Carolina, USA, said this particular diner always tips well and has been generous even during the pandemic.

But they were certainly not expecting his generosity after a meal.

After dining at the restaurant, the man left an envelope containing the tip for his $10 meal (AUD $13).

Inside was a note, and over $2,000 cash (AUD $2,575), which he wrote should be split among all the staff working.

“The gentleman that left the tip is a regular who comes in at least 6 days a week,” Eggs Up Grill Managing Partner Adam Bair told Fox News via email.

“The gentleman paid for his $10 meal and left the envelope with the money and the note without waiting around for his server to open the envelope. We tried to catch him in the parking lot to thank him, but he had already left.”

The note revealed four servers at the restaurant received $400 (AUD $515), with the rest of the cash split between other staff based on the hours worked.

While staff considered him a generous customer, no one was expecting the enormous tip he had left.

“It was very surprising. It made a huge impact on all of us above the monetary value,” Bair wrote.

“It made the servers feel appreciated during a very turbulent time with COVID. Their tips have gone down tremendously and I know the money was very much needed. It was perfect timing.”

The tip was allegedly left as part of the ‘Just Be Nice Challenge’ which encourages diners to leave large tips for their servers.

Now, staff are keen to see the man again to say thank you.

Waitress Selene Montalvo told WYFF4: “He paid most of my bills this month, and that’s why I can’t wait to see him to really thank him.”
