Series about a couple that runs a public bath with a "special" service. The husband knows and condones it due to it being a family business he took over from his mother.There is a flash back where the husband caught his wife's cold and ended up damaging his sperm count so the option for a impregnation special became available to the regulars but he ended up getting her pregnant instead.(Other people's wifes became employed there too (think one wife was dark skinned))
