I’ve yet to be forced to use a QR code menu. I have sometimes had the alternative be looking at a large menu board over having a menu card in my hands, but even many restaurants will happily hand you a menu card on request. That said, given the circumstances I haven’t left a 50 mile radius of my house, so it’s possible it’s different elsewhere.
