It was only meant as a light hearted comment. Both my grandmothers were alive up to recent times and they still referred to currency in predecimal terms even though we had thankfully done away with that over forty years before, "You paid ten shillings for that!"... My father rented a small plot for growing vegetables and that was still measured in rods and perches. I like to think of myself as a good European and use the metric system after all it is so much easier than all these peculiar and strange measurement systems.
