Not wasting a cent on any performer who engages in this nonsense.
Good. You stick to your guns and never go to another live show again.
I'm sick of people like you trying to film shows and blocking my view. Instead of me being able to enjoy a show, I have the experience stolen from me so while some narcissistic tool holds their iPad above their head to take shakycam footage with abysmal audio, and all I can see is their poorly exposed image on the iPad's screen.
It's a LIVE performance. The entire point of the exercise is what's happening right in front of you at that very second. Whatever you're recording on your phone or iPad is a miserable substitute. Try actually paying attention to the show instead of fiddling with your widget.
