Not sure I understand you. I did ask to reschedule to the next day, and Darius got snippy, saying I shouldn't have scheduled if I couldn't do it. They did reschedule and I did do it. I had 30+ shops. But if their shops are in demand, then that's the way it goes.
Do not read so much, look about you and think of what you see there.
