Today I was seater. I take the guest to the table and explain the buffet:"et voila, l'entrée, l'entrée, plat chaud, dessert". She:"attendez monsieur je vais le traduire pour les autres... l'entrée l'entréé plat chaud dessert". WTF!!!
Being a polyglot isn't easy, you have to fight against your accent because they don't understand you. French is a very sensitive language in this matter and the Frenchies in general aren't the most patient people (in contrary to Italians for example). But even in my motherlanguage I have a kind of accent ("You speak it perfectly, but where do you come from") so maybe it's me.
