A Wantagh waitress was in disbelief after receiving the ultimate holiday gift from a customer: he left a $1,000 tip on his $500 tab.

Danielle Gray, who works at Hemmingway's, says, "I saw the one and the three zeros, and I was like, 'No way, this can't be real.'"

It was.

The customer is a regular at the restaurant who wanted to remain anonymous. Gray says he has picked up the tab for other diners in the past.

The waitress was planning on using the extra cash to buy gifts for her 2-year-old daughter.
