Do you dread asking someone a question for fear that they can never answer without pulling out their phone and having you stand there FOREVER because they need to show a pic?

Me: "Paul, do you want a green one or a red one?"
Paul: "Red, hang-on, I have a picture of the red one"

I just needed to ask another guy a question, who is just the same and so I walked a good distance away and came to him as if I was in a rush (I wasn't) and prefixed my question "I need a quick yes/no answer". He still went for his phone so I kept walking and shouted "text me"  

Drives me nuts.

Yet when it comes to important communications, they forget that they have this device.

They want a simple answer from someone and they'll spend 20 minutes tracking the person down for a yes/no.

Tried to get them on Zello, which I use in the USA. Phone becomes a walkie talkie but they can't be bothered to install the (free) app.
