Shopping around the holydays can be pretty frustrating. Most stores are packed with not-so-patient shoppers, the lines are huge, and you end up wasting a lot of time. To make their customers’ shopping experience more enjoyable, Germany’s largest supermarket orchestrated an unusual surprise for all shoppers. It took 13 hidden cameras, 9 talented cashiers and a beat-boxer for everything to come alive, but the result is the best in-store Christmas campaign I’ve ever seen. I don’t want to say more because I don’t want to ruin the surprise for you, but I will say that this beat will stay in your head all day!
