Can't see how it's a 'minority interest'. We all have to eat.
That's just it. We should take the time to think about what we are choosing and being served, in terms of its provenance, how it is prepared and presented, what different nutrients it gives us, tastes, culinary traditions etc. Most of the time we just comment, "hmm that is OK or that isn't too good" without giving much thought as to what we really expected.
I'm not saying everyone should be a foodie when dining out like me, but why shouldn't the actual food and how it is cooked become a big topic of conversation during the meal? We do care.
