At fourteen I started working at a convent altar bread department full-time through the summers, primarily as a baker (baking communion wafers and hosts) but sometimes as a cutter (cutting out the same, one at a time). The ovens were like pressurized waffle-irons, some plain and others with the circular designs engraved in their plates (agnus dei, crucifix, IHS, etc.). Each baker was responsible for 2 or three ovens per shift, starting at 6am. It was hot, steamy work, and the gummy by-product that squeezed out of the ovens every time they closed was gross, but-- nothing like the jobs a lot of you guys have described.
(Sorry, Frank: my only tools were tongue depressors to scrape the gummy gook out of the oven gutters every time they were closed, and scissors to trim the sheets-- though I wish I could find a picture of the cutting machines, the round, sharp hole punches in various sizes, and wonder now if/how they were sharpened.)
While the bakers were baking, the cutters were cutting, punching wafers out of the humidified baked sheets from the day before. At the end of the morning and into the afternoon, everyone gathered to count and roll and package the day's finished wafers in waxed paper-- like counting and rolling coins, only much more slippery.
My parents required me to save half the money I made; my first summer of work, I used all of the other half to buy my first guitar, a Guild I still have.
(Thanks for the contest and the thread, OP. I'll let others have a [better] chance at the knife; not an entry.
