I read the original article and was somewhat dismayed to read that:
"The hot drinks urn is on the Fritz as we near Newcastle."
I'd never heard this (derogatory) expression which apparently dates from 1902, however I guess it's a term referencing Germans, cockney rhyming slang, (Fritz Lang = bang?? Perhaps), or some reference to "The War", Fritz/blitz=destroyed, "kaput"??
80 years on I thought we'd all grown up a bit, no need for Top Gear style reporting in a supposedly serious consumer magazine.
With that sort of journalism Which? appears to have sunk since my parents read it in the 1970s, seeking out the best household appliances.
As it is I'll form my own (revised if necessary) opinion
when I next travel on that route.
