Supermarkets are time-consuming. For a simple breakfast, you’ll need to go to the back of the store for milk, and then return to the central aisle for a lifestyle-appropriate cereal. This forces you to invest your time both in walking around the shop and choosing from among different products- the more time you spend inside, the more likely you are to grab things you hadn’t thought of buying. And while the average stay in a supermarket is 55 minutes, factors like music can change this. Fast-paced music is played when the supermarket is crowded, to make you shop faster and leave sooner (crowded stores lead to more stress and less impulse buying). On the other hand, slow music is played in empty supermarkets, helping you linger in the aisles.
