Ugh, god. The worst was the Wednesday night when I saw Wicked.
Some person in the row in front of me decided that right in the middle of "As Long As You're Mine" was the PERFECT time to turn her cellphone on, open it up, and use the light to read the bios in the program for the ENTIRETY of the number.
What the heck, man?. Read your freaking playbill at intermission or after the show. It was SO annoying. I was ready to slap her very, very hard.
I also agree with the people who have mentioned audience members talking over the overtures. I'm here to enjoy an evening of music and acting...so LET ME LISTEN TO THE MUSIC.
Also, when people just leave playbills lying around to get trampled on after the show. Those cost money, people! And are collectibles to a lot of us Broadway freaks...
I know I have more, but am at a loss at this moment.
"Cages or wings, which do you prefer?"-- Tick, Tick...BOOM!
