Interview for a nanny job - the mum looks me up and down carefully, sighs and says, "oh dear, you're very thin aren't you? Have you got an eating disorder? Because I really haven't got time to be dealing with any of that nonsense". Her husband looked absolutely mortified. (I didn't have an ED, and I wasn't even that 'thin' - about 9st!).
First job, aged 16. Got taken on as a sales assistant in the newly opened electrical dept of a well known department store. Interview was with HR, so didn't meet other staff until my first day. Manager was really pissy with me, despite me doing everything he asked. At the end of the day he asked me to wait behind, and once all the other (male) staff had gone, basically told me that he HATED working with women, that we had no place working in electrical retail, (we were flogging tv's and fridges ffs!), and that he'd nearly refused to take the position, "once they told me they'd hired a girl". Being 16 and shy, I just muttered 'sorry', (one of my great regrets in life!).
That story had a good ending though, I carried on working there, he was obnoxious to me, but couldn't fault my work. After a year, he moved to another store, and was then sacked for theft 

. I, on the other hand, was made manager of the store he'd left, (at age 17). Lol.
