I do not carry a cellphone, but I own an old one with no data plan that remains off and in a drawer except for when used for things like this. I am not sure I have run into any stores that require 2 factor. Mostly just official stuff like banks.
My work has multiple systems that require 2fa on a regular basis. It's actually quite annoying, and the alternative options to 2fa don't work for every system.
