Mistresses worked in the supermarket as sales attendants. They worked all the aisles, making sure everything was okay. The manager was always on their neck whenever there was a problem, and they did not want problems with him. He would shout at them and make them feel like worthless beings. One time, a customer accidentally knocked down a bottle of detergent, and the manager went off on them. They decided it was time to teach him a lesson. They took him to the urinal, where they made him their human toilet. He had to drink all the piss that came out of their body.
