Back when I studied, I worked part time in a local store. I was responsible for juice, soda, beer, wine, and other bottles of alcoholic drinks. I was responsible to order them, and to manage and refill remains over the week. Being a small shop, I also needed to be a jack of all traits. At times I had to have an eye on refilling vegetables, and fruits. At other times, I needed to refill milk, or answer inquiries from our cashiers. That said, there are some lessons I learned in that shop that helped me find my way once I joined my first job. Here are some nuggets from that time.
