Sure. One time I was a mystery shopper at a fast - food place. I ordered a burger and when it came, there was a huge dollop of ketchup in the middle of the bun, like a ketchup volcano. The staff just stared at me when I pointed it out, completely clueless. It was both funny and a bit concerning for the store's service quality.
A friend of mine was a mystery shopper at a hotel. She checked in and requested extra towels and a special pillow. The staff brought her not only the extra towels and pillow but also a whole bunch of other random things like a box of chocolates, a teddy bear, and a bottle of champagne. They thought she was some sort of VIP mystery shopper. My friend had a great laugh about it.
One typical shopping funny story is when people misjudge the size of something. Like buying a huge piece of furniture without measuring the space at home first. Then they struggle to fit it through the door or find a place for it. It's really funny to see them trying to figure out what to do.
Last holiday season, I was in a store when a little girl was begging her mom for a toy. Her mom said no, so the girl put on a pair of reindeer antlers and started dancing around the toy, saying she was a magical reindeer who needed that toy to fly. It was so cute and funny that the mom finally gave in.
Once, I saw a man trying on a huge, furry hat in a shopping centre. He looked like a yeti and started doing a little dance in front of the mirror. Everyone around was laughing.
Once I ordered a 'large' sweater. When it arrived, it was so huge that it could fit three of me! It was more like a tent than a sweater. I took a picture of myself drowning in it and sent it to the seller. They were so amused that they offered me a discount on my next purchase.
I went Christmas shopping with my friend. We were looking at ornaments and she accidentally knocked over a whole display. Ornaments were rolling all over the floor. She was so embarrassed but we couldn't stop laughing as we tried to pick them all up. There were other shoppers helping us while laughing too.
Sure. Once I was shopping for shoes. I saw a pair that looked really cool on the shelf. When I tried them on, they were so tight that I could barely walk. But I didn't realize it until I walked a few steps in the store and almost tripped. Everyone around me was trying not to laugh.
Sure. Once I went to a grocery store. There was a little boy who was trying to reach for a box of cookies on a high shelf. He climbed up a bit on the shelf itself and when his mom saw him, she screamed. But instead of getting scared, the boy just grabbed the cookies and said 'Mission accomplished!' with a big grin.
A memorable one was when a group of teenagers decided to have a mini - fashion show in the middle of the mall using the clothes from a clearance rack. They were posing and walking the 'runway' while the store clerks just watched in amusement.
