Sex workers descretion?

Prostitutes, strippers, and porn stars have the chance of coming across someone who has a girlfriend or is married, obviously.

Say a man comes in to the strip club and the stripper (for whatever reason) knows he is married and is not supposed to be there per his wife. Should she still give him a lap dance and entertain him or deny him and respect the relationship?

Same with prostitutes and porn stars, should they sleep with the man or respect the relationship and deny him?

What is comes down to...is their priority to do their job and leave whatever the man's personal issues are out of it? Or should they take it upon themselves to respect the wives wishes?

What would you do?
