The Wales international is now a first-team regular at the Liberty Stadium, but the 28-year-old has revealed that he dabbled in food service.
"I did all sorts," Williams told the Daily Mail. "I was the worst waiter you can imagine. Really. People would be left waiting for ever to order and then I'd bring them the wrong food. I worked at Drayton Manor theme park for a while, doing the ring toss and the sledgehammer. I worked at a bowling alley too."
Williams and his teammates are preparing to take on Liverpool this Sunday.
