I like it that a ritual designed to provide the *illusion* of cleanliness, only adds to the skeeviness of the the whole regrettable episode. Part of the purpose of the 'table shower' is to superficially whisk away the back hair, pubic hair, flaky epidermis, and semen from the last Al Goldstein looking pervert who was on the table just three minutes before you. This is all done *while* you are on the table so any contact point with the table - your scrotum, perineum, and anus, for example - are places where this dude's humors and eczema are now gathering in a warm pool, creating a fertile breeding ground for the infectious bacterial and viral creatures who are seeking a new host.
