I worked as a maintenance or "piss" boy at a local swimclub. I can easily say this was the most physically demanding job I've had to date, and I got paid minimum wage ($5.15 at the time).

The tasks I was required to do included: sweeping the pool deck, scrubbing the pool deck for stains, taking out garbage, cleaning the bathrooms, cleaning the "birdcages", and any other bitch work they required us to perform!
