We need to extend the ADA to protect people who are not technologically-abled.
Other people covered under ADA who might agree: partially sighted/blind people (yes there's screen readers and such but a piece of paper is often simpler to handle), people with reduced mobility or tremors in their hands, and probably more.
This is a really good point. I'm surprised the box office cannot print it for him for a fee at Will Call, which might be the solution here.
Good luck with that under the current administration.
Or who don't want to sell their soul to Google or Apple.
Accessibility benefits everyone.
