Ban all talking and phones!

"This was a fantastic show spoilt by the few individuals that for some reason find it impossible to sit and watch a show without chatting all the way through it???/ WHY?...also staff tried very hard to stop idiots who refuse to stop taking pictures and filming the performance..why when they ... catch them dont they throw them out?..One woman was told 3 times to stop filming every time staff walked away she just continued. All this is very distracting for people who want to enjoy the show."
