That's a very important point. I have a number of friends who pull out their phones the moment it pings them, and nine out of ten times it's not important. And, usually, the tenth time where they say 'I have to answer this call/message' it's not in the least time-sensitive enough that they can't wait 10-15 minutes. I'm still not sure how to deal with this, because everyone does it so I'm the weird one for finding it rude and disruptive to the conversation. The only thing I've come up with is to politely ask the people I interact with regularly and the people close to me to not check their phone during a conversation we're having. (interestingly enough this usually sparks a conversation where they also express a dislike of constant interruption...)
