When I was in high-school, I worked at an office supply chain in the "Business Machines" department. I sold computers, adding machines, Palm Pilots (the first revision!), printers, cables, you name it. Aside from helping customers, I had to stock those items on the floor, take daily inventory, complete cleaning/organizing projects, set up new displays to specs (Planograms) and take on whatever other tasks my managers wanted me to finish. Eventually, I was promoted to "Business Machines Lead" -- which came with a sweet $0.75/hr raise.
