Reading the comments here, seems like countries have really good integrations with QR menus, like Apple/Google Pay, out here, in India, all we mostly get is a download for a PDF hosted on a Google Drive, that is a bunch of images and is a 50-100 MB download (because why compress?), and then you have to constantly pinch to zoom and pan through the document, I have some 40-50 of them on my phone because when I go again, I won't remember the menu already exists with me, I'll download again.

The ones that are decent are also not that great, the JS code that runs constantly stutters and its basically a delivery menu, allowing you to place orders, seems off putting in dining out.

Have had a hard time convincing waiting staff to give me a physical menu, and I keep hearing a response, we have QR, as if that's making them somehow tech-savvy. Its a restaurant, I don't think you ever need to be tech-savvy, just serve good food. Doubt they'd be able to reduce waiting staff by introducing these tech features anyway.

Worst is McDonald's (IND) attempting to force people to use the large TV touchscreens to place orders, and two or more people (helpers) keep helping you use it and eventually place the whole order for you, and it lacks customizations like no tomatoes etc, so you anyway give up and go to the counter. It's possibly an attempt to reduce work staff, but seems forced on to the customer. And the touch latency is just... resistive touch phones were a lot better.
