What if the person promising the first thing is not the person doing the second thing?

Do people really do this now? Watching a movie on my phone is so suboptimal I'd only consider it if I really have no other option. Holding it up for 2 hours, being stuck with that tiny screen, brrr.
I can imagine doing it on a plane ride when I'm not really interested in the movie and am just doing it to waste some time. But when it's a movie I'm really looking forward to, I'd want to really experience it. A VR headset does help here but a mobile device doesn't.
Working from the hypothesis that people generally don't have seconds they are willing to give away to anyone who calls, but they are busy to varying degrees.
Unfortunately “hack” became a catch all word long ago. Just look at “life hacks”.
