I gotta say, I disagree with this piece. I, for one, love QR code menus. I can pinch zoom rather than squint at a menu with small/unreadable fonts in dim lighting. I don't need to badger the already exhausted wait staff on a busy night when they forget to drop us a menu or two. When orders are taken online, rather than awkwardly force a friend to not go to the bathroom (or take their kid to the bathroom) until a server can take their order, they can just order and then go. I do think restaurants should handle payment themselves and have the option for paper menus or menus posted on a wall if needed, but otherwise I'm a fan.
You’ve built a beautiful straw man that I’ve never seen in real life, rarely if ever have I encountered a menu with tiny font that is unreadable, I’ve never been to place that seated me and didn’t bring the menus at the same time. I’ve not experienced the bathroom thing either even in large parties, but it doesn’t sound awkward… if someone says they have to go to the bathroom they go, just tell the waiter this person will order a little later… or they call tell you what they want if they already know.
Just because you have good eyesight doesn’t mean everyone else does
If you have something that can read a QR code you also have something that can magnify text.
I dated a girl with poor eyesight, and absent a digital version her method was the phone flashlight and holding the menu very close to her face. So the physical version was workable, but a pinch to zoom is still more dignified.
