Recently, a café in London made a different kind of lunch special offer to its customers. A three-day promotional event was held that allowed customers to trade a short workout for free lunch. It was a pretty good offer as the workout required was only six minutes long. Hungry customers had options of a minute on a rowing machine, a minute on a spin bike and a minute on a treadmill. Also included was a minute of sit ups, a minute of lunges and a minute of body-weight squats. Customers took a thirty second break between each exercise. It was a perfect combination of things that fit perfectly into a lunch break. With most breaks being an hour or less, the customers only had to use a small portion of the time to earn their free lunch. Once the workout was completed customers could choose from smashed avocado on toasted whole meal bread or a delicious grilled chicken breast burger that came with tomato, red onion, and garlic mayo. It doesn’t sound like a bad deal and plenty of customers showed up to give it a shot. After all, when a free lunch is offered, people will show up every time.
