I can't believe the sensitivity of the last 3 people who replied.
Have you never offed a guy from a bar and then gone back to the same bar the next night and offed someone else, while your previous night's guest sat looking on? How do you think the latter felt? Don't forget that this is a job for these guys and they hope to be offed every night, and not necessarily by the same person.
Also, if you go to a sauna, do you not try different guys each time? Do you think that the one you had previously feels rejected? Rejection is part of the game.
