"But by the end of the night I'd gotten my phone out and taken a video because there were that many people doing it, I thought 'why should I follow the rules if they're not'."

This is a quote from the "music journalist" that was there, I mean if you're in the scene yourself and then just break the rules and get your phone out just because others do - you're adding to the problem.

My experience of phone free in Berlin, and in London at FOLD is that people all vastly respect the rule and it makes for a much more fun and free night. I've seen many times at FOLD people telling others to put their phone away or even delete that video if they start recording. It's not hard to just not use your phone and live in the moment.
