* I intentionally don't use my phone at restaurants. In fact, I often prefer to leave it in the car.
* In my area (rural America), a lot of businesses have really poor websites (noticeably worse than urban areas). Nearly all of the QR menus are down right terrible.
* There's a good chance some one thought it'd be great to have a bunch of collapsed sections and add a terrible animation. I need to manually expand each section and deal with the terrible animation repositioning the screen.
* For those less tech savvy businesses, they probably just uploaded a PDF of their menu. Bonus points if the menu is scanned in on their 15 year old printer/scanner combo.
* Finally, there's the group of restaurants that have changed menus but either (1) forget to update the website (2) accidentally have multiple, differing copies of the menu
