That way it can be considered that the food is part of the price of the drink.
98% of the UK population can speak English, so I'm not sure where you got that idea. Clearly every part (maybe some small, uncelebrated village breaks the rule) of the UK has a language spoken by virtually the entire population of that region.

If you are struggling to say that England is the only country in the UK that sees most of its population still speak the language of its ancestral roots, then I suppose that's true, but when English is the most commonly used natural language across the entire world I'm not sure that is much of a feat.
What does any of this have to do with the discussion at hand?
Much the same thing has happened here too (the local watering holes struggling and failing, that is), but that isn't even considered newsworthy at the local level, let alone a message that has spread far and wide. English pubs, for whatever reason, are the only ones that have consistently caught grander attention.
But there will always be someone living under a rock, as they say.
