So, I've been asked for a concrete example, presumably referring to
how to define fast_food/restaurant/cafe *mutually exclusively*. I
looked at the current wiki definitions for all three tags, and these
are the best, new *mutually exclusive* definitions I could come up
with, in the form of a flowchart:

If you have suggestions to improve the flowchart, that's great - the
main point is that, I believe, it is possible to precisely define the
definitions of cafe/amenity/restaurant. And, I would suggest a unified
flowchart in this case makes life easier than comparing three
separate, vague wiki pages, or by doing "mental experiments".
