the only times its happened to me is years ago a new young trainee kept flashing her knickers at me, her desk had no modesty panel and I sat opposite. Being an upstanding gentleman (cough) I discreetly said I could see things she didn’t want me to see, she smiled and next day there were no knickers. As a married man, I ran a mile.
Second time was more recently when I did a building induction with two others, one being a not unpleasant lady joining a different team, a month later we were swapping emails and she asked me to meet in one of the basement rooms, always empty, once there she proceeded to drop her troosers and asked me to do the same – the bare faced cheek of it.
Both were complete loons.
