Reality about clichés : Are French people rude ?
Sure, if you spent a week in Paris you probably met rude people.
Yet, you have to remember that Paris is one of the most visited city in the world, so Parisians can occasionally get tired of tourists.
However, you will mainly meet nice people if you come with an open mind and try to speak some basic French (simply saying “bonjour” instead of “hello” can make a huge difference).
The same is true in other cities. Although people are usually friendlier in small cities than in capitals like Paris. People are basically the same everywhere. If you smile, they will smile back.
