This question is lifted from author Sahar Sabati's informative Ask an Author series, which ran from 2015-2016 and included responses and reflections from English-speaking authors from around the globe. Since I'm often asked these questions by readers, I have republished my answers here with Sahar's kind permission.
You can read about my most embarrassing moment in my chick-lit novel A Dash of Reality because Mel’s silky-harem-pant-wardrobe-malfunction is plucked from my own experience. In real life the incident occurred on a summer evening in January, on a service station forecourt, while I juggled a bunch of flowers, a box of chocolates and a cup of coffee. When I finally got my pants retied—yes, tied and retied, with one of those doubly double granny knots—I turned to see four men, each sitting in their vehicles, laughing their heads off at the sight of my thonged bottom! And there was no dashing Jack to step in and save Lee’s dignity. Instead, my husband, who was waiting for me in the car, was darling enough to point out that the service station forecourt was bound to have a surveillance camera, and thus, my bottom was likely to be plastered all over Youtube within the hour—I haven’t found any evidence of it yet, but if anyone does, please let me know! In any case, rather than empathising, my husband found the whole incident hilarious. So there it is, my most embarrassing moment.
