Window fitter Steve Whitehurst, 47, showed security his ‘member’ after a female manager raised the alarm.
Steve had been buying $400-worth of stuff at Scotts Menswear, with girlfriend Mandy Shenton, 46, and her 18-month-old grandson.
Things got a little awkward after the store manager asked him about a bulge in his pants.
“The manager started arguing with me. She wouldn’t let it go. I just kept telling her that it was my penis.
“Eventually I dropped my trousers in front of everyone and just stood there in my boxer shorts and said, ‘See, I’ve got nothing to hide’.
“But that didn’t satisfy her. She kept saying, ‘What’s that bulge?’”
Steve recalled: “I dropped my boxers. He shook his head and ran out and spoke with the manager. I heard her say, ‘Please tell me he’s got something down there,’ and the guy said, ‘No’.”
He called last Sunday’s outing the “craziest experience of my life” and has complained to the company, owned by JD Sports.
Mandy said: “It was so humiliating. What they did to Steve was disgusting.”
