I have to agree with this. The most common clashes I run into mapping towns
in Australia;

bakery/cafes (technically you could do amenity=cafe, shop=bakery)
general store/cafe
general store/fuel
general store/post office
pub/hotel (I tend to create two nodes, in roughly the right places)
pub/restaurant (in the country, I take the restaurant as assumed - every
pub serves meals at least some days of the week)
cafe/bar

A general solution that would solve these and other problems would be a
relation to group parts of the same business. That way, you could have the
expressiveness of precise tagging (eg, "is there a bakery near here? yes.
is there a cafe near here? yes") but easy rendering: show one icon, and the
renderer can decide whether it's a cafe or bakery icon.

+1, I also see it like this. If you want, group them into a site relation
afterwards. The argument: one osm object for one real life thing doesn't
work anyway. What is "one real life thing"? Why should the pub and the
hotel (restaurant / telephone / letter box / ...) be the same thing? If one
business has several shops, is that one or several "things"?

Thats just another very specialized single-purpose tagging scheme that
cannot be generalized to connecting multiple institutions in one POI. At
least not if you still want casual mappers to be able to decipher such a
thing. The idea of a semicolon-delimited 2D-matrix distributed over multiple
tags for general tagging makes my hair stand on edge. :-)

The original example wasn't mine, but I think it is very common that a pub
has much later opening hours than a restaurant. Having both as part of the
same enterprise is a british speciality if I remember my visits correctly.

And mapping them as separate POIs is the only practical and human readable
way we currently have available, that's the point. :-)
