That’s because we have had exposure to it while growing up, in one of two ways: as mini-entrepreneurs, delivering newspapers, cutting grass, or babysitting; or as young employees, working at a fast-food joint, or packing and carrying out groceries at a supermarket. As mini-entrepreneurs, we learned that, if we delivered a wet newspaper, we wouldn’t get paid.
If we didn’t show up on time for babysitting, we wouldn’t be called again. As young employees, we learned that, if we flipped the hamburger onto the floor, or if were rude to the customer, we would get fired. Importantly, we also learned that there is a relationship between the quality of our service and remuneration.
