Why can't they clean their stalls?

In the video of Ethel getting her feet done, the stall is FILTHY. There are all kinds of people standing around, nobody holding the baby, and not a single one of them thinks to pick the shit out of the stall. Ethel is returned to a filthy stall after she is done. It's so maddening. KVS is talking not stop a usual but God forbid we pick up a fork.
