Which brings us back to the point that your comparisons were horrendous and not the same thing at all. A computer is vital to a business. A personal mobile phone is not vital when in a cinema watching a film.
While in my career now it's not since we have a NOC that handles all support calls after hours, in my previous job as one of three members of the entire IT/IS team that made up a national organization...when I was on call every 3rd week my mobile phone had to be answered.
Not responding for 2 hours is an eternity when you have customers looking to hand over at least $200,000 to one of the sales reps I supported. My phone vibrates, I get up and head to the lobby.
Imagine the heart surgeon that works as an independant instead of in a large group. He is always on-call.
Yes, not EVERYONE has these needs and today I just turn off my phone entirely in a theatre. There is nothing that can't wait 2+ hours for me now. Before I couldn't and I also had to have a laptop which fortunately was later replaced with just an iPad with me.
Also since I was 1 of a team of 3, I was really always on-call. Sometimes the guy on-call was out of signal or missed the call. If we didn't see a response in 15 or so mins then one of us would have to pick it up. This didn't impact anyone at the movie. I had to get up much less than that family of 4 running to the lobby every 15 mins for another coke or bio break.
What do you do for a living? You have to be either working something like a clerk position or worse or still living at home and in school to have such a loss with these concepts.
Yes you can say exactly that. I buy a mobile phone for my convenience, not anyone else's. If I want to turn my phone off then I will and anyone who takes offense at that has a problem. If you are unable to go a couple of hours without the use of your mobile phone then you have a problem.
You just made it clear you are probably the most unimportant person on this planet.
Most that are more important are GIVEN a phone for the convenience of the company they work for. Those that run the company use their phone for the convenience of their customers/employees.
It's rare when one's cell phone need is entirely personal.
