Whenever I see someone in a current British television show use "inches" or "feet," I'm reminded of the HN metric mafia that insists that the United States is the only place in the world that uses imperial units.
Even Wikipedia will tell you that's false.
There’s no other place on earth I can invite 100,000 people to disagree with me. Exception is maybe a public office. (Which the vast majority of people shy away from, for just this reason)
