There was no question? But I'm glad your grandma has a phone. It must feel very good inside to have such privilege in this day and age! It's really not that hard to understand not everyone can use a QR code. ADA laws exist for a reason. I'd totally understand if you're just a 15 year old who's trying to feel superior, but you're being very ignorant to the less fortunate. Everyone would love to be able to experience all there is to life, and to gatekeep it behind a QR code is rather nonsensical.
An internet capable phone in 2023 costs close to no money. Again, if 3rd world countries can maintain an internet presence in the face of global imperialism, grandma can scan the fucking QR code with her dinky $20 android
Physical maps exist. Other people exist to ask for directions. Cash exists. How do you think people functioned before smartphones were a thing? Jeez dude, it's like you think that just because it's 2023, the ways of doing things before smartphones are suddenly not an option because of them. Again, not everybody has access to cellphones or wants to use them just to read a friggin menu.
But plenty of ACTUAL people don't for whatever reason. Furthermore, plenty of people (myself included) find it ridiculous to have to take out my phone to read the menu. Why you act like the world should bend and conform to your personal wishes and experience is beyond me
