I was the youngest member of a professional kitchen staff and being untrained did the routine jobs like buttering bread for sandwiches , slicing tomatoes and cucumbers, cleaning salads and other greens, peeling potatoes and carrots and cleaning fridges.
I was 16, most of the other girls in the kitchen were trained and in their early twenties, but they were a nice bunch, and as one of them said, "We all remember what peeling hard-boiled eggs for hours was like, so you leave those to me and go and help Jean set out the cold buffet for lunch."
I learned a lot from those nice girls, especially what a difference it made to be treated kindly and not as a skivvy because you were just out of school.
