Rapper DMX  stopped at a Waffle House in Greenville, S.C., for a late-night meal on Oct. 31 and grabbed a mop from an employee to finish the guy’s dirty job for him.

“I was in a good mood and felt that I would do that for him since it was 4am and [the employee] had been working all night,” DMX explained.

Word is the employee told the rapper he was a big fan, and X was so touched, he wanted to do something nice in exchange.

“The minute you get too big to mop a floor or wipe a counter,” X said, “that’s the exact minute you have life f—ed up.”
