Yes, that's so true. I once went to get a deposit back on behalf of a friend (a Kiwi) who'd rented a flat in France. The landlord agreed - unusually - to return the deposit in full, but mentioned in passing that the bathroom walls were damp because :
"It seems that your friend had a strange habit of taking his showers standing up."
I did wonder if there was something lost in translation, but no, that's really what he said, and it seems that the French, particularly the older generation, do indeed take their showers sitting down in the tub. It could explain a lot, but yuck, let's not go there!
