Shift Work Secrets Revealed!

Hey everyone, I work the night shift at a local supermarket. It's pretty quiet and slow most of the time, but last week something bizarre happened that left me feeling both excited and nervous. One midnight, as I was stocking shelves, I found a note tucked inside one of the cereal boxes. The note said, 'Hey, thanks for keeping this aisle neat! - A Night Owl.' It made my day because it's usually just me here, and no one else ever leaves little surprises. Since then, every few days, there’s been another note or a tiny gift like a candy bar or a sticker. I’m loving the attention but also wondering if it could be someone playing a prank or maybe even an employee having a laugh at my expense? Does anyone have any thoughts on how to figure out who this mysterious night owl is without being too obvious? Is this normal, or am I just getting way too excited over small things in life?
