Still can't see the problem! If the girl is £70, £90 or whatever then just take the right cash! If you are someone than might drop an hour rate down to half hour, having seen the girl, then make sure you you have the right combo of notes to do either. We talk about girls being lazy but it seems some guys are too lazy even to ensure that they have the correct change! My local snack van man is also pissed off with people giving him £20 notes all day long for a £2 or £3 sandwich - whereas I have a stash of pound coins in the car. Given that a lot of girls tend to be either money grabbing or disorganised - and we all are aware of that - why would you expect it to be any different when it comes to expecting them to have change?
