When I think of places where phones aren't a problem, I think of bars and restaurants.
So why on earth would you even need to make them phone-free...?
People are socializing plenty. I've never walked into a bar or restaurant that's full of people where they're all on their phones. It doesn't even make sense.
Really? I see this all the time. Maybe I'm going to all the wrong places. I see "couples" on their phones, I see groups of friends on their phones, etc., etc. Maybe different parts of the country / world?
