Wrong city for me but I have done office outcalls in Vancouver. He is a regular for me and I am thinking you might not have to much luck if you are new to a lady for a office outcall. For my guy it was simple, it was his office and I just walked in, locked the door behind myself and went to his conference room, he is a big time financial adviser and acquisition guy. Bj under his desk while he bought or sold a company on the phone. People on the other end must have wondered why the long pauses between sentences
Think it depends on your office. If you are the boss and send everyone away and no worries of consequences then not a problem. Otherwise could spell trouble for you, your job and the lady.
Think long and hard before going down that road.
