Karen

Minding your own business, you browse the stock on the shelves, trying to find that one product you really want. As you keep looking, you bump into the shelves and accidentally knock down a box of cereal, and immediately put it back, only to feel nails digging into your shoulder.

"EXCUUUUUSE ME!" a shrill voice screeches. "How DARE you ignore me!"

Oh no, it was the dreaded Karen.
