Hahahaha I was picturing this idea before asking tbh... We sometimes get some customers who hate the QR's, or claim not having phone/signal/whatever. I'll lend them my phone to check...
I'd refuse to touch your phone and insult you for the offer. If you don't have a paper menu the question of me giving you money is already off the table; the food is forgotten and my new mission in your restaurant is to punish you with my vindictive attitude. If enough waitresses complain about obnoxious boomers giving them grief, I think the business owner will eventually wisen up.
QR code links to menus are bad, sure. I'd still rather eat at ten places that have those than one place that has you.
