And restaurants. Some months ago I went to one with my children. No smartphone to be 100% with them. "The menu is only on this QR, and if you cannot scan it, I cannot tell you what to order, because we have so many options".
Discussion
Did you stay there?
Restaurant menus on webpages over QR codes are such a horrible UX, even

Yes, because we had already ordered the drinks for then, and I had 2 hungry children. But I never came back.
It happened in 2 different places. I put 1 start in Google Opinions or whatever was called, for both places. One of them replied "we'll have paper menús from next week".
But you're right, it's very bad UX even if you have a smartphone with big screen. Scrolling up and down, and changing tabs... WTF.
