I can tell you one about cars but the other person on the phone might of been embarrassed, or felt really stupid.
My daughter was hiring a car and the hire company rang up asking to speak to her the conversation that followed......
Me.....No, sorry she's not here, I'm her mum can I be of any assistance?
Him...No, not really I need to speak to her.
Me ....OK, I'll get her to ring you.
Him....You need to be 25 to hire a car from us, you sound too young to have a 25 year old daughter (Oh, I loved that bit)....do you know her date of birth?
Me..... Well, it's funny you should say that actually, yes I do, I just happened to be there at the time.
Silence the other end of the phone.....and then the penny dropped and apologies from him. I just thought it was very amusing.
