"Nathan Fillion when I was working at a movie theater.

Guy bought 6 large popcorns and a bunch of smart waters when I thought, “man this guy is loaded”. He was wearing a hoodie and glasses so I couldn’t quite tell at first. I eventually said, “Hey you kinda look like this guy Nathan Fillion”

He took off his glasses and said, “I sure hope so.” I stood at attention and said, “Captain”

He replied, “As you were, Browncoat”. Coolest moment ever."
