Paul Potts' call of duty

'Britain's Got Talent' winner Paul Potts has already returned to his job as a mobile phone salesman.The opera singer - who won £100,000 on the ITV show last month and has signed a recording contract reportedly worth £1 million - was roped into working during a visit to Carphone Warehouse in Bridgend, earning himself £1.50 in the process.Paul told BANG Showbiz: "The other day I went back to the shop where I worked in Bridgend just to see my friends. But it got quite busy so I ended up helping out and working behind the till until it calmed down."I think I'll have earned myself about £1.50."The 36-year-old says he thinks some customers recognised him from 'Britain's Got Talent', which was watched by 11 million people during the final on June 17.He said: "I got quite a few knowing looks and stares, but I just got on with it because it was so busy."Despite his success, Paul still refuses to rule out returning to his old £13,000-a-year job full time, and is currently only on sabbatical.

He said: "I take it each day at a time because I know this might not last."

Paul's debut album 'One Chance', produced by Simon Cowell's company Syco, hits record shops next week.
