When you’re out strolling on the strip, you will definitely see guys handing out business cards. They’re known as card slappers who advertise escorts that will come to your room for entertainment. Prostitution is illegal in Las Vegas so never think that they are what these card slappers say. Chances are that these girls will rob you the first chance they get, normally when they ask you to “freshen up,” and take off before you know it.
