I have a question I hope someone who lives in France won't mind answering. I have a French student living with me this year. She's telling me in France no one says "thank you" or expects to be thanked for normal daily life such as when someone holds a door for you or buys you dinner or cooks you a meal or hands you something. Se tells me "thank you" is only said when someone does something really big for you so that you're indebted to that person. I'm telling her that culturally, particularly in the south, we say "thank you" every time someone does something for us. I don't recall ever having the thought when I've been in Paris that people just don't say "thank you". Is she correct, or is this just the opinion of a 17 year old?
