"Walk in and give us your BEST dance moves for 5 seconds," read a sign displayed on the entrance door of a coffee shop in Massachusetts.

In our world, as it exists today, social media virality ensued.

Coffee Milano Cafe in Middleborough got the idea from a pizza shop that pulled off a similar promotion—to help get people through the door and see the lovely, comfortable interior and great coffee.

But they never imagined it would go viral, with 7.6 million views on TikTok alone.

"We just thought it was going to be a small thing for the people that come in every day," Olivia Svenson, barista and social media director of Coffee Milano Cafe, told ABC News.
