Lets just say that if I was a money grubbing female/male and I saw two people of the opposite sex working on me right before I konked out...a lawsuit would be in the back of my mind.
I would think that this is a smart office policy. I have heard of dentists interviewing a female for a position in the office after hours when only the dentist is there. As soon as the female interviewer arrives she demands a check or else she will sue for sexual harassment. What else can the dentist do? He will save more money cutting her a check for 10K than to fight the suit and counter it.
Watch your backside like you were in prison.
