The staff was rude and locked me out of the office. After I signed in, I was informed the wait was over an hour. I asked the staff if it was ok for me to step out for a phone call. They said as long as I was back inside before 5pm. I came back at 4:55pm and the door was locked. I knocked repeatedly and could hear people inside, but they never allowed me back in.
