I found this place to be quite pretentious, which is not my style (and frankly, should not be anyone's who is in the service industry). It was not particularly clear "how this place works", and in addition, it was not evident that the staff was very willing to helping a new customer who had not been there understand its nuances.
Honestly, I wanted a nice cup of coffee with my mother, and we walked out without one because no one acknowledged us for 5 minutes. When I asked a person behind the counter if this is where we could place our order, she responded in a rude tone advising that, as I could see, she was making coffee for someone else and could assist me in a few minutes (which sounds far nicer than the experience was). There was no friendly greeting or explanation. Get over yourselves. You are in the service industry, treat people with dignity and respect, and they will pay for your product, it's that simple.
