I was at one of your supermarket checkouts recently, waiting for a price check
on Generic Brand Toilet Rolls - Six Pack. To fill the awkward silence that accompanies
these occasions I asked the seventeen year old cashier if she thought the word
'mileage' would ever be replaced by 'kilometreage'. She replied,
'It's unlikely. It's just a generic term relating to the ratio of distance travelled
to fuel consumed. You could be talking about kilometres per litre, miles per
gallon, even leagues per ton of coal if you wanted. It's all mileage.'
