In it, the waiter can be seen rapping along to Nosetalgia byPusha T before beatboxing - while the restaurant goers look on baffled, as they thought he was about to sing Happy Birthday.  But while they initially appear confused, they appear to be on board by the end of the unusual performance and cheer loudly.

Hayden Lowe shared the clip, joking: "Just ya average waiter" at the restaurant in Santa Fe, New Mexico.  She explained: "We thought he was about to sing Happy Birthday to my 80-year-old grandma. "He closed the door and said 'there's a birthday' and stood in front of us all and began this amazing performance.

"[He] just caught us off guard."

She added: "Nothing was said, [he] closed the door and just began."

People were left in stitches at the unusual situation, as one viewer joked: "The fact it was for her 80-year-old grandmothers birthday makes the video 10000 times funnier." Another commented: "He's making eye contact with everyone like he's doing a presentation at school."
