At 5'8", I'm average height for a man, so I do occasionally sit behind someone who is much taller than I, and I either try to make the best of it or try to get a different seat. I was at Parade on Tuesday night, and the person in front of me was tall, but I managed to see around him. There were only two times that someone incredibly tall sat in front me and I couldn't do anything about it. Once was at The Iceman Cometh in the late 90s. Unfortunately, that performance was sold out and the tall person took his seat just as the houselights dimmed, so I was stuck trying to look around him. The other time was at My Fair Lady in 2018. I was in the second row, where the seating isn't raked. I asked if I could be moved and was simply told, "no."
I find it frustrating when people aren't that tall, but have hairstyles or wear hats that obstruct my view. I had two situations like these last November. At A Christmas Carol, the woman in front of me had a hair style with hair braided on top of her head that was several inches high. I asked to be moved, and my companion and I were moved to much better seats. At Death of a Salesman, the man in front of me was wearing a hat. As the show was about to start, I tapped him on the shoulder and asked if he would mind removing it as it was blocking my view. He replied that he would not because he didn't want his head to get cold. I tried to move at intermission, but was unsuccessful. It's these situations that are more problematic for me than someone being tall and unable to adjust their height.
