This happened yesterday at my local Costco, and I’m still confused by how aggressively triggered this guy got over a sample.

They were giving out those pineapple teriyaki meatballs. I don’t actually buy them because they're not great for you, but I’ll always grab a sample when they’re out. The employee had just put out a fresh tray and there was zero line—literally just me and one other guy who grabbed one. I went up, took two, scarfed them down, and started walking down the aisle.

As I’m walking, I notice a guy parked with his cart in the middle of the aisle, staring dead ahead. Every few seconds he’d glance sideways at me, then quickly snap his eyes back straight ahead. I figured he was just waiting on someone, so I didn't think much of it.

Right as I walk past him, he shakes his head, scoffs, and says: "One at a time, bro… one at a time."
I was totally thrown off, trying to process if he was actually talking to me. When it clicked, I said, "They’re unlimited… I took two. What’s your issue?"
He instantly starts yapping nonsense and gesturing, saying "Come on, let’s go get some tacos" in a tone that made it pretty clear he wanted to fight. At that point, I just walked away.

He wasn't even waiting in line for a sample, there was no crowd around, and taking two samples is completely normal anyway.

Just an utterly bizarre interaction. Has anyone else ever encountered a self-appointed Costco sample monitor?
