FWIW, my first H experience was also at Meatpacking and I also made the appointment online. I did not receive any confirmation email, but did tick off to be reminded by text and email in advance. The day of my appointment I got worried because I did not hear anything, so I ended up calling about three hours in advance and spoke to someone who confirmed that they were seeing my appointment in the system. I ended up receiving a text about an hour in advance.
When I got there (I got there about 15 minutes earlier than my appointment time), the guard took my name, passed me some hand sanitizer and told me that my “assigned SA” would come to get me but I’d be free to walk around and browse. Ended up walking up and down the store for about half an hour before I headed back to the main floor and a SA who just wrapped up with another client saw me and asked if I was waiting for someone. I said I’m not sure given it’s my first time and SA mentioned they could help me.
Also, FWIW, while the SA who helped me in Meatpacking was professional, nice and gave me her card, I had reached out a few weeks later after shopping and did not hear back from them. I ended up going to Madison afterwards as a walk-in, where I met a great SA, who has been nothing but kind and responsive. My SA at Madison actually approached me when they saw me looking at items and we’ve kicked it off since then.
