God yeah...the way I look at it is if you arrive and the girl does not look like the girl in the picture and you are not happy then walk. Why would I stay with someone and pay good money, if I did not find them attractive or someone that I would not pick up on a night out.
Other reasons that I have walked have included walking in to a hotel room and the ash tray over flowing at the side of the bed. The room stank and also the girl looked as if she had just got out of bed and had a wiff of BO from her.
