It’s hostile to the experience. It takes me out of why I went to a restaurant I the first place. I want to sit down and focus on my present company and forget about my digital life. This isn’t a new experience, Red Robin and Ruby Tuesday have/had a tablet checkout system that was a chore to use. I started removing restaurants that used similar systems from my rotation because they ruin the experience.

It's hostile to your experience; others (me included) find QR codes quite handy and saving time and efforts

QR codes are a tool. It isn't the fault of the hammer that sometimes they are used to kill people. Likewise it isn't the fault of QR codes that many times they are used for something that isn't useful (at least they can't kill). When I'm at a museum I love the ability to scan a QR code and get a lot of detailed information that wouldn't fit on a sign - but often I just want the small sign and then I move on to the next exhibit.

a great combination is a short summary with a QR code for more info if you want it. It doesn't have to be rocket surgery.
