Saw him in St. Louis a little while back. I was mad at first because he had like two shows and they sold out in minutes. He kept selling out shows and they were adding more and more throughout the weekend and I finally got one.
And yeah they enforce the no cellphone thing hard. Hell, I went to a comedy club a few months back with a C level comedian and they enforce it there too. It ruins the effect of the joke if several people in the crowd already know the joke that's coming up because they saw it on IG/FB/YouTube. And it shouldn't be a big deal for people either, unless they get an important call. But for people trying to record the show, damn just sit back and enjoy the show without having to let everyone on social media know that you're there.
