Your list feels a bit like r/WhereDidTheSodaGo, that is those silly infomercials that make it seem like putting dishes away in the cupboard is some monumental task. I mean "find the scanner apps"? Are there phones nowadays where the code scanner isn't just built into the camera app? I don't think I've used a dedicated scanner app for at least half a decade.
I find QR menus annoying when you're at a place where you specifically want to forget about your phone, like a nice restaurant for dinner, but I don't think they're some huge amount of work.
