Before my (future) SHL and (current) SMJHL fame, I held multiple jobs. 
My first job was at a skate rink as a skate guard. This was perfect, as I was at the rink for practice anyway. It was great to basically never leave the rink after school and on the weekends. It also sucked because I had to clean out locker rooms, bathrooms, common areas, etc. This was when I first realized that women's bathrooms have an extra trash can in their bathroom stalls that had to be emptied - GROSS.
The best part of the job was actually skating around and patrolling during open skate/ice sessions. During "teen night," all the high schoolers would be out skating the rink. This was when middle school aged Ja'Aj would skate circles around the guys, and teach the hot older chicks how to skate - this turned me into the Casanova that I am today.
