We've all had that moment in the office where we wanted the floor to open up and swallow us, but some have had worse times than others, it seems.
Pollster YouGov asked British workers for their most cringe-inducing moments in the workplace, and it wasn't disappointed: it said the results ranged from the mundane, such as forgetting someone's name, to the "downright bizarre - involving mouldy food, fire engines, and in one instance, a sex doll".
One person assumed someone was pregnant when they weren't, while another mistook someone for the opposite gender. Common mistakes involved sending emails to the wrong people, and (naturally) accidental "all staff" emails.

I was supposed to be conducting a short service for the burial of ashes on a Saturday afternoon but I completely forgot about it because I had gone shopping with my family.
Turned up at the wrong venue in a town 100 miles away from where I should have been.
Then there were the ones we can put down to lack of experience...
