I have never, to the best of my knowledge, owned a telephone that can open QR codes, and I'm neither interested in finding out for sure, nor buying a different telephone. I've largely stopped going to restaurants anyways because of the outrageous unannounced and mysterious fees that many are now tacking on (I'm not opposed to paying what it costs to produce fine dining, but tell me the cost up-front), but I also will not go to a restaurant that won't just hand me a damn menu. I'm just a drop in the bucket, and no doubt nobody is missing my custom, but who knows, maybe there are more like me.
