As a teen I saw an ad in Blockbuster's window saying 'apply within', so I popped in and they said to come back at 5pm or whenever to interview. I said 'oh, have you got the time now?' as in, what time is it, trying to be polite though. The woman got really annoyed, saying 'no I don't have the time, I just said come back later'. Of course I made it worse.... pointing at my wrist, 'no, I mean, have you got the time now', anything rather than seem rude just saying what time is it! After asking about 4 times (this was before mobiles and I've never worn a watch!) I eventually got it from her and wondered off to sit on a bench for 4 hours. Didn't get the job, surprisingly!
Once an agency called with details of a nanny job, in central London so 90 mins travel from me- which is a lot when the job is a 12 hour day!- I eventually met the mum in a coffee shop after spending about £15 over tubes, trains and 2 buses to get there. turns out the job was pretty much a check list of things I'm not looking for in a job- shared care, nannyshare, older children, having to get a taxi between two family's homes each day, half the pay the agency told me, a driving role.... essentially the worst job possible. that one was the worst, but if I was to list every agency job I've been sent to which was unsuitable (or I was) I'd be here all day!
Oh and there was the babysitting I turned up for when after being there 5 mins the mum waltzed out of the bathroom starkers, graciously asked if I needed anything then slowly walked back in..... not an interview as such but unexpected! I never sat for the family again!
