Besides mowing the lawn and whatnot during my early teens, my first regularly paying job was as a short order cook at the "Treat" restaraunt in Shippensburg. I started my Junior year of HS (15 years old)
I would take the order, go to the kitchen, make it, then serve it. Was a great first job, as it taught me a few things.
1. The harder you work, the more perks you get from management later on.
2. I never want to work in food service again.
3. I never want to deal with the general public once again.
4. Work my ass off so that I don't get stuck in a food service managerial position like my bosses there did.
