locals can't see what the problem is
We have about the same situation over here; small towns and local norms it seems.
The locals really do not care about big city concerns; in fact you kind of get the notion that you really do not belong here in town and things are just fine the way they are. You certainly know you are an outsider.
The colour of the fuel nozzle handle cover does not really matter; whatever is handy and for the most part, there is not a plastic cover installed at all, (well perhaps pieces of one). Again, it is the view that coloured covers are a big city thing.
These days, fitting all the pumps with a small diameter spout seems to be more the norm as small fits all; in the past, it was the large diameter everywhere and you were expected to knock out the filler restriction if you had a "new" vehicle.
With most vehicles here being petrol, about all that happens is that the petrol grades get mixed up in the storage tanks. As a driver of a premium unleaded vehicle, you figure you maybe got a load of water. If it really is water and the winter, the gas line freezes and you are soon stopped. You haul the vehicle off to a heated shop and all works fine; then you drive outside and it runs until it stops again.
The first fix is to pour methanol into the gas tank to absorb the water as draining is never easy. Also a pint of methanol with every tank full in the winter can be good practice. If you can, it is also a good idea as a matter of routine, to fill up when the tank gets to about half empty as insurance against a full tank of wet or off spec fuel.
