Has happened to me several times as well, sometimes I am the one waiting and sometimes I am the one pounding (read about one of those times right on here). It goes with the territory, if there is an opening before a booking, they take the person who is there and if the booking shows up, wait or switch........standard practice at most places unless you have a good relationship or a higher end place. Is always good fun knowing that the girl has been warmed up and often is pretty horny and ready to go. And as long as she showers in between.
