I suppose for me, going to a restaurant is not a matter of "efficiency". I go there to socialize with friends, to enjoy the atmosphere, to interact with people.

I suppose for me, going to a restaurant is not a matter of "efficiency". I go there to socialize with friends, to enjoy the atmosphere, to interact with people. If service is slow, then, yes, I get annoyed. However, I don't think I ever go into a restaurant thinking, "I wish they would make restaurant ordering more efficient." If I want that, I go to a fast food place or place that does takeout.
