I think I understand your viewpoint, but personally have a different opinion. I’m not going to a restaurant to socialize with the waiter; although some of those interactions can be pleasant it’s still just a functional transaction to me that can go wrong and could be be optimized. My main focus is the people I’m going to the restaurant with and the food/drinks.
QR for the win for me, but I agree fully that most of those apps kinda suck. I hope time will fix that.
