Smartphone

Given there are cameras everywhere it becomes likely the airline/airport has a better chance of defending itself if they show you were on your phone and not paying attention to what you were doing and hurt yourself.

After all that, I've had to deal with assholes who argue with me right there on the tarmac when I politely ask them to put their phone in their pocket for the 30 seconds it'll take to walk up those damn stairs.

Please do not use your phone while you're walking across the tarmac to your plane.

when you're on your phone, you're not paying attention to what's around you.

I've also had to chase after people who walk away from the aircraft in whatever direction they feel like (even toward other planes) to try and fit the whole plane in their selfie.

I've have good laughs at people who try to be 'sneaky' and hide their phone under their boarding pass, or hold their phone awkwardly at waist-level so they can film, or put their phone down only until after they think they're out of my eyesight.

My concern is with the passengers that wave their phones around without a care in the world, as if begging for me to intervene, and who think that they're out on the tarmac for any reason other than simply boarding the damn plane.
