Not the commenter you asked, but in the United States pumps with one hose are common. All the grades of petrol are dispensed through the same hose, and you just select which one you want.

Some pumps do have two (or more) hoses, especially those that have multiple types of fuel (one for regular petrol, and one for diesel). Some pumps for also have separate hoses for each grade, although they seem less common to me.
