Each spa is different, unless it is one of those places that require you to basically submit a application, then your dealing with what is essentially a business that is based on volume.
I once had a mms text me she had a new young girl she wanted me to try, I make an appointment and when I got there I got bumped.
Or worse my first experience showing up at 58 st, where I'm there for apptm. , I get there and a guy is standing directly in front, calling and then ringing the bell, he did not even give the monger who was leaving much room to pass .
Some folks are rude, some have no formal upbringing, most are arrogant , combine that with a business, trying to get as much customers as possible........
