This is literally the funniest thread I've ever read!
I work in the Tesco staff canteen, and we have to go and get loads of individual chocolate bars from the shop floor to put in the vending machines. So there I was, getting about 20 of each chocolate, when the little glass front comes off and sends a whole shelf of chocolate bars cascading to the floor. It was really busy that day too, the self serve boy and some other poor boy on his break helped me put it all back up. I must have been so red and was shaking so much!
Another time, me and my mum were going to Currys, and we were trying to go in the automatic sliding door, but it wouldn't open! We were stood there for ages trying to work out why it wouldn't open when we saw that it had a massive 'Exit only' sign, stretching across the whole door. We then walked into the right door, but it was so embarrassing!
I seem to do embarrassing things on a daily basis, I just can't remember them all!
