I visited a mathematics research institute in Bonn, Germany sometime in the 1990s. In addition to offices, each floor had a small kitchen with ceramic coffee cups, coffee-making equipment, and a prominent sign stating that everyone was responsible for washing their cups after use. So I was surprised to find a mountain of unwashed coffee cups piled in the sink.
The mountain grew higher each day, and eventually teetered precariously. I was afraid to go near it, lest my breathing set off a cup avalanche and topple them onto the floor.
I asked around, and learned that the culprit was one person.
One day, I saw the culprit in the kitchen, adding to his monument. I pointed out the sign about washing one's own cups, and said I was curious as to why he didn't.
He politely explained that he was from Poland, where (he claimed that) washing dishes was women's work. He said that he expected the female staff or the female mathematicians to wash his cups.
Since I hadn't yet spent any time in a Buddhist monastery, I most likely gave a response that isn't printable.
