It's best you don't do walk ins. Call the number and make an appointment instead. This way you don't diminish the quality of the other guy's session in progress. And you also do not cause her to interrupt the session to answer the door. She wants to capture whatever customers available as times are tough in this economy. When you have places that still have claims eligibility, usually other men goes to these places first before they visit New Beauty that aren't able to. She seemed like she is trying to strike a balance between ensuring her client present for session does not get interrupted (door closed and dark) but yet do not let potential walk ins waste income opportunity too (you walking in and interrupted the other guy instead of calling in an appointment).
One woman show only, no secretary to help.
And for this specific session, you did not come back to partake, and you did not call in to book an appointment and you caused a lesser quality session for the dude you interrupted.
