Plus, apparently, everyone has their phone out all the time. Again in my experience (which is all I have to go on!) people don't pull their phones out at the table unless they're bored enough or pissed off enough to disassociate. Someone looking at their phone for longer than it takes to read a text is a sign to me that I need to move things along, someone's bored or feels left out.
If people aren't absorbing the information, aren't engaging with the world, aren't chatting and bantering with each other and are looking at their phones too much to pay attention -- is anyone having any fun?
