I am In a hotel on a course and have just been woken up with a knock on the door ( it's 1am), so I shouted through the door "who is it" and the young girl said "hi is it Martin" so I opened the door and she realised I'm a woman in my fluffy pjs so quite clearly not a Martin, she just apologised and got on the phone to someone all I could hear her say was what was the room number as she had it wrong, she was dressed up like she was coming in from a night out which I though was strange seen as I'm at a service station hotel, so now I'm laid trying to get back to sleep and it just occurred to me ... was this woman a call girl? I can't think what else she would be doing?
