Why the fuck do you keep talking about cultural norms? "Cultural norms" aren't homogeneous. This cultural norm bullshit you keep spouting is just a way to isolate people from your ideal world that exists in your head. Did you know that some people have different religions? Did you know that some people like macs more than PCs?
My fucking intentions are to get some food. Why are you putting so much value into what is essentially a person who takes food (from a cook, you know, the person responsible for making your food and the actual star of the establishment) and transports it less than a 100 ft radius?
