Customer service for a trucking company. I had to keep track of what customers needed what products and when, and the rearranging of orders, doing reports, dealing with customers, dispatchers, managers, receivers, it was non-stop for 9 hours a day. I loved it, but the drama that went on in my department made me quickly hate where I worked. And one day I almost caused a contamination (luckily it was caught by a driver and cost the company nothing), and was suspended for a week without pay. A few weeks later a terminal assistant manager I worked with didn't pick up a dozen shipping containers before the deadline and cost the company tens of thousands of dollars, was promoted a month later to terminal manager. That really killed my drive.
