Not that I've got anything against the French, but they did invade us and take control of the land and government, or at least the French named Norman did! But I'm not surprised the French came out top, or at least when the article seems to be focused on the Parisians. The polite Japanese visit Paris a lot, or used to -- so so sure about these days. But anyway, I became aware of a phrase used by the Japanese that meant something like, "Paris Syndrome".
Ok, just found this -- maybe it just affects the Japanese?:
"
Paris Syndrome (Pari shōkōgun) refers to a kind of cultural where the Japanese find the reality of Paris doesn't live up to their romanticised expectations. They arrive expecting elegance, charm, politeness, and cinematic beauty — but instead they might encounter brusque service, crowded streets, litter, and a generally indifferent or hurried urban attitude, especially in places like the Metro or tourist-heavy areas.
The syndrome can lead to symptoms like anxiety, delusional thinking, dizziness, and even depression. In severe cases, the Japanese embassy in Paris has reportedly had to assist distressed tourists — arranging hospitalizations or even early flights home."
Then we have Londoners -- oh, someone give me strength! The article posted by the OP, in regard to the UK, seems to centre around London. I met an American girl in London -- we became engaged. Not on the same day, I hasten to add -- I don't work that fast! But anyway, at the time she said to me, aren't they polite in London? I thought to myself, you are kidding me. Personally, I think most Londoners at some of the most impolite people in the UK. I made my point clearer to her when I took this girl to the Midlands, where I come from, then further north.
But anyway, here is a news report about Londoners.
