I'm dying with laughter at all the responses here!
I've had a few embarrassing moments over the years! Here's 3!
1-As a bus driver, there was a long queue. I just got my right leg into the cab while clinging to the steering wheel, and the back of my trousers split wide open, revealing knickers with Minions all over them, right in front of everyone, who all laughed! I wasn't overweight, and my trousers were quite loose, so I've no idea why they ripped! The second I was back at the station, I had the embarrassment of running to the office and having to spend a few seconds punching in my passcode to get in with my bum ... and Minions... hanging out of the back, I went to my locker, which was in the staff canteen, having hysterical laughter from various colleagues, then ran straight to the loo for a change of trousers!
2-Another time I was working in a shop, dealing with a woman who looked and sounded like she'd come out of the Dallas TV show, and I accidentally let off a huge fart, burp, then hiccup with a second of each other! I wanted to floor to swallow me up! Thankfully, the lady had a brilliant sense of humour as I stood there, dark red and apologising madly!
3-Working in a cafe, which was doggy/pet friendly, A man came in with the most gorgeous little Pug dog. I was over him like a rash ... the dog, I mean, not the man!... He picked up little Eric and put him in my arms, who then decided to wee all over my t-shirt, and it trickled down to my leggings! I thought it was hilarious, and the man was very embarrassed, but I had to go home for a shower and a change of clothing!
