I don't have a cell phone, because I consider that the costs outweigh the benefits. Recently I started experiencing more often the effects of people assuming that everybody has a cell phone.

* I couldn't scan QR codes at restaurants to see the menu, after the pandemic. The server was able to find an old paper menu but warned me that prices had changed, and I had to order without seeing the new prices. This is less of a problem now as most restaurants went back to paper menus.

* My place of work recently installed 2FA that assumes we are always near a phone, and they don't want to provide an alternative such as a yubikey, so I cannot log on to the network unless I'm at my office or at home (where I have a landline).

* I use a car-sharing service and they want to switch to an "app-only" system for booking cars, which I guess will require me to install some kind of Android virtual machine on my computer.

Truth be told, those are minor annoyances in the grand scheme of things.
