I expected more professional service from front-line staff here. Firstly, their box office seemed fairly disorganized when it came to ticket pick-up: the box office attendant disappearing multiple times into the back before eventually another person emerged to help with the process after the line-up had grown to fill most of the available space.
Unfortunately, we also had no support from the ushering staff inside the theatre in dealing with the person sitting behind us who was taking multiple pictures very audibly throughout the entire first half, and then proceeded to leave their phone turned on with audible notifications. My companion had to turn around multiple times to ask them to stop. Even though it was clearly disturbing patrons in our section, there was never an usher who came by to address the issue, and I got the distinct impression that we had been left to fend for ourselves.
The building could also use better signage on the outside to direct people around to the main entrance. We had approached it from the public square side and ended up going the wrong way around. Luckily, we had arrived about an hour early so we weren't pressed for time.
I am a front of house professional who has worked at other theatre venues for over 10 years, many of those in management. It is regrettable that this particular experience here as a patron is giving me serious doubts as to whether or not it is worth the hassle and expense of attending any future concerts here.
