Actor Justin Long shocked diners at a popular New York City restaurant when he posed as a waiter. After finishing his meal at the eatery BLT Fish on 4 March (11), Long got up from his table, purchased one of the restaurant's t-shirts and began working as a staffer, much to the amusement of his friends.

A source tells E! News, "He just started picking up glasses, cleaning tables. One lady was asking him questions about the menu and he was just making up answers...His friends kept saying, 'Make him work, give him a hard time.' It went on for over an hour. He was really working. He'd come back in the kitchen, grabbing menus, filling waters, asking questions. The chef was laughing at him. Justin was totally cool."

According to witnesses, The Going the Distance star left all his tips to the other employees. (MC/WNWE/KL)
