Cha-Cha Japanese Cafe

My wife and I came here after a long day of work and we called ahead of time to let them know we were coming just to make sure we wouldn't have to wait since my wife was pregnant and her job refused to give her any breaks at work to eat, so she was starving. They said it was fine, that we wouldn't have to wait because there were plenty of seats available. We arrived right before a family of 10 (estimating) and the staff chose to seat them instead even though we were at the door first. They asked us to wait outside just a little bit longer, that one of the tables were about to pay and they will seat us there... That's when 5 more people came that turned out to be friends of that family of 10, 10 became 15, they didn't even have enough seats, they pulled out stools out of nowhere, I guess possibly from the kitchen or from the back, they added stools for them and kept us waiting outside. We decided to wait anyway and the group finished eating and paid but sat there for hours after that just talking and laughing before getting up to leave. Usually when people are waiting and we have already finished paying they rush us out or ask us to leave so that more customers can come in, but not this time. They said nothing to them... My wife started to get a migraine and she got dizzy from no food. She miscarried that night. Don't know if it was related, but I feel like it was.
