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.
