My first job was working in a local corner shop. Amongst my duties l was tasked with using a pricing gun (a name which makes it sound a lot more exciting than it is) to label tins of food with a price sticker. The process of manually pricing was very time-consuming and if the shop owner decided he wanted to reduce the price of peas to 25p that week, it meant manually repricing everything again!

Thankfully, technology is more advanced these days and no one will ever have to spend hours...
