I worked for a company where I set up thousands of chairs for concerts and plays that took place there, I did Janitorial Duties, sold Concessions, took tickets, worked security, worked in the box office, was involved with Public Relations, counted money for tills at the end of the night. I did everything, it depended upon the night, on what I was doing, Some times I was just ushering, other nights I did box office, and concession work. It was all included in my job. I was never hired on as a manager though. What would you call that position in a company?
