> French culture is a rare culture where shop owners won't be afraid to tell off/talk back at customers that don't show a basic level of politeness.

My favorite French shop anecdote (I'm American): Went to a bakery in Paris. Tried to order "Un croissant, s'il vous plaît". Shopkeeper responded (in very lightly accented English) with "I'm sorry, I don't understand what you're saying". I wasn't mad or offended, in fact it's one of my favorite memories from the trip.
