Whilst I like the sentiment, and when I have parties at my house I try to encourage the whole "leave your phone by the door" thing, I don't really like this.<p>When I'm in a pub, I'm generally not on my phone, and I'm quite conscious of trying not to use it unless I'm sat waiting for someone or similar. However, I always have a phone with me in case of emergencies (which means being reached, not just making calls out), and I'd hate the idea of that being blocked.<p>Not just that, but I'm often on-call (with either a phone or pager) but will still go out and socialise, in this situation this establishment is one that has to be avoided.<p>Good idea/sentiment, bad execution.
