Almost thirty years ago when I was a student, I knew a guy who was of Swiss/American parentage, and had been brought up in a Swiss monastic boarding school (Franciscan?) from the age of 11.
He was as messed up as you would expect given that kind of upbringing, but was one of the cleverest people I ever knew. I think he’s now somewhere very senior in the EU.
Anyway, he always claimed that the Swiss produced two different kinds of Toblerone – the good stuff that stayed in Switzerland and the junk that went to the UK.
No idea if it was true or not.
