I personally never take out my phone DURING concerts. It's usually off so that I can save battery to call for an Uber when I'm done. However, I do occasionally use it to text friends to find them when I'm in the venue but before the event starts. This would completely prohibit that. More importantly, I like to rock out at concerts (halestorm, the pretty reckless, etc.). This would potentially discourage me from doing that, because I would be worried about that bulky bag popping out of my pocket and subsequently getting stepped on. This directly hurts my appreciation of their music and the event. I dislike this so much that I will boycott any artist who does this.
