It was at the Chicago Theather and it was the Chris Rock show back in 2017. I bought the ticket, I don't believe that it had any special restrictions [this was a long time ago], the ticket had no indications about the "phoneless"/phone encasing demand. The event page didn't say anything about this. However they were trying to force this. I refused
Why did I refuse? The Bataclan attack* happened less than 2 years before this and mobile phones did [it was reported at the time] help people communicate for help and escape. This is a big venue, and I certainly don't trust a venue who doesn't trust their ushers who can't get people to stop filming. Think they're going to know how to call the cops/handle an emergergcy? lol.
What happened? Since I was denied, I asked for a refund from the venue. The main security guard corralled me against the wall, waited for the manager, the manager argued with me and refused refund [even despite the ticket saying nothing about this, their overall policy said nothing about this [I checked to see if I could bring my small camera with me]], when the manager left to get an artist rep she felt the need to "ban me" to another security guard, they got a "artist rep" trying to argue against me using "well this is the artist's preference". (Why they brought out the stupid artist rep is beyond me)
Ultimately I lost that 80$ and will shit talk Chris Rock, any venue, and any artist who uses the yondr device.
