Let’s be honest: The amount of work to print out one or two pages and put it into one of those menu thingies is near zero. They are also quite cheap, you can keep around multiple printed menus without breaking the bank. This is not preventing restaurants from changing their prices
What makes you think they’d change prices on a whim? More likely they’ll change the prices based on whatever they learn from the browser fingerprint of whoever at your table is first to scan the code. Better get the intern to go first, just in case.
They can also easily change their pricing when there’s a higher demand or any other whim.
