If getting accustomed to French bathrooms (have you experienced the separation of toilet and shower?) isn’t difficult enough, there’s always the challenge of correctly asking permission to use them.
Avoid the mistake of saying “Puis-je user les toilettes ?” (My I wear out the toilet?) and stick to one of the following instead:
Puis-je aller aux toilettes ?
Je peux aller aux toilettes ?
