Years ago I lived in a room and shared a bathroom with an actress who lived on the same floor. We had to put a gold coin in a meter if we wanted to take a bath. The actress was even poorer than me because I once found her sharing her bath with all her clothes to save on laundry costs. (I would use the laundrette down the road every Saturday afternoon). After that encounter I would make her donations of bath money. For some reason she kept this, probably because it is still loaded with a coin.
