Obsessive phone use is just out of control. Saturday, I was driving down a local street toward a signaled intersection. A car up ahead at the intersection was just sitting there despite the green light. The car only started moving when the signal turned yellow. I guess the clown had to finish writing his Tweet before moving.
And, yeah, phones really make a lot of public events suck, especially live concerts. It's bad enough you're going to get price-gouged for the tickets. People sticking their phones up in the air for much of the show ruins a good bit of the experience.
I used to watch movies in commercial cinemas on a frequent basis. Smart phones are one factor why my movie-going has dropped off radically. If I do go to a cinema I try to pick an off-peak time when fewer people will be there. Any benefits of sharing a movie experience with a large crowd are easily cancelled out and worse by the behavior of selfish idiots. Phones are just one of several distractions in a movie theater.
Worst kind of movie-going experience: any "film festival" event where video cameras of any kind are present. It doesn't matter if the people with cameras are students from a community college. The bigger the festival equals a worse crowd. Smart phones up in the air is a given. Anyone with narcissist, attention-whore tendencies will get on their worst behavior. These types of jerks will try to yell-cheer, yell-laugh or make any other reaction noise louder than anyone. It's like a contest. They're all trying to try to draw attention to themselves and prove they're "enjoying" the show more than anyone else in the room. We could be watching a low-budget movie that's objectively pretty crappy and these people will react like it's the greatest movie they ever saw. The behavior is so shamelessly lame it makes me want to vomit.
