@rob11563 @lrvick @tphinney @Jennifer I get this kind of thing a lot, too.
I don't really carry my phone around with me unless I need to phone someone while not at home (which isn't often, it can wait, and other folk can wait for me).
Your phone can be nicked or damaged and it's got all that info on it and is big and expensive and everything, and it's always tempting to fiddle with it, or take photos rather than do things unmediated.
But the strangest things are suddenly not possible. There was a burger van which refused to serve me the other day. I was there, they had spare burgers, I had a kind of money they accepted, but they wouldn't serve me because I didn't have the app, literally just to order the food, and I didn't have my phone.
They're all trivial things -- I can always try to remember my phone if I know it's going to happen -- but it's weird.
My phone spends most of its time plugged into the wall at home for when I have to interact with these weird companies (until I find a competitor!)
