My favorite part of the article:
“When I was asked to perform this mission I was intrigued. It sounded like a significant challenge. I had done the work before (as a professional restroom-attendant) in high-end nightclubs and expensive restaurants and they tend to come with a certain type of client. I’d never had the pleasure of working with a fast-food clientele.”
