One thing that many players can do from time to time is lose their players club card, occasionally a player will leave it in the card slot on a machine they have been playing and will walk off only for another player to remove that card and put it at the side of the machine where it could get lost! If you do lose your players card then make your way over to the comp club desk and the staff there will be able to issue you with another one very quickly, many casinos will ask you to select a PIN number so only you can access your comps.
