People are in love with Costco for all sorts of reasons. It has amazing prices on bulk purchases of everything imaginable, from toilet paper to oatmeal.

On any given day, you can flash your membership card at the front entrance before strolling right inside for a free mini appetizer-filled “lunch.” That’s when the sample food stations are set up throughout the store, tempting you with all sorts of tasty bite-sized treats for free while you shop around.

If, however, you’re in the mood for an improv-style concert performance while you eat, they’ve got you covered there, too! When a young YouTuber who uses the handle “hyp3r247” noticed a piano salesman start playing Adele’s “Someone Like You” on the piano, she made the decision to sit down on the piano bench next to him.

This mischievous woman wanted to take part in all the fun! At first, you can see the young woman quickly and nervously glance around her.

But, then her legs quickly start to move and sway with the mellow tones of one of Adele’s most magical songs. Then, without missing a beat, the woman puts her hands gracefully on the piano keys and joins the equally talented salesman in an impromptu Costco concert duet!

While shoppers checked off items from their shopping list, they were shocked to hear such a delightful surprise. The crowd just had to stop and listen.

They were drawn in by the popular song, but stayed for the amazing performance! What an incredible unexpected treat while they were out shopping.
