This never happens to me. Damned building codes:
A shocked Russian couple had a narrow escape when a woman in a bath tub came crashing through the ceiling and into the middle of their living room.Rozalia Valiakhmetova had been relaxing in the bath upstairs when the floor gave way, dropping her and the bath tub into the flat below.
She said: "I had just dozed off and then I heard this huge crash and realised what had happened. The bathroom floor just collapsed under the bath and I came crashing through the ceiling of the people below me.
"They seemed as shocked as I was when they saw me lying there naked in the bath in the middle of their living room."
Most people are unsure about the etiquette of greeting unexpected nude female visitors of the waterborne variety, but it's really quite simple. A tip of your hat and a hearty "Enchanté, Mademoiselle!" is all that's required.
