I can understand the suit on the AH tour completely.
I had a similar situation happen to me at the HOTE show in St. Louis. I got my phone out even before the opening act started and was just going to check messages and this lady came over saying to put it away. I was shocked. She was with the venue security and said if I didn't put it away she wasn't going to page Eagles security and have me removed. It really started things off on the wrong foot, to say the least. It had me miffed before I even got settled in my seat.
For me, there is no valid reason to do that. I know this isn't the phone thread, but it still applies. They just got way too stuffy and lost some of the fun or even just decency. I was told if I needed to use my phone I needed to go outside.
I don't know who was to blame for this idea. I'm sure both Don and Glenn agreed on it and Glenn had to sign off on it, but whoever's idea it was, was a bad one.
