It’s as if we wear uniforms

I was playing Magic at my local gaming store tonight, and had the following exchange:

Me:  “Do you have an extra Endless Ranks of the Dead?”

Opponent, pointing at a drafting table:  “No, but ask John.”

Me:  “Which one’s John?”

Opponent:  “The guy in black.”

Me, seeing five:  “That … doesn’t really narrow it down.”

Opponent:  “In the black sweatshirt.”

Me, seeing three:  “…”

Opponent:  “Sitting next to the guy in the red shirt.”

Me, seeing two:  “…”

Opponent:  “With the beard.”

Me:  “Oh, him.  Thanks”
