People poke fun that I prefer paper docs (notably boarding passes/tickets). However, last night I tried something new that involved starting a rental time and stopping it on my phone. That was the only way (despite it being a physical object that knew when I was very likely done with it). Sure enough I'm not getting data and can't access the button to stop it. The company refunded my few minutes of troubleshooting after I asked, but it makes me very wary for if my phone dies or freezes or glitches. Paper doesn't do that.
