Not as simple as that.Discretion is the word. There are escorts whose friends dont know what they do as a job. A guy said hi to an escort and her friend ( not an escort) gave her a real hard time as to how she knew him as she knew the girl didnt know anyone else in the city. Was sitting having a cogfee with a lady from here when a guy came over and started talking quite openly to her as a client. He had no idea who i was or my relationship or not with the girl.....idiot.
So unless the escort initiates it, just walk by.
