Normies see a guy holding up two fingers asking for three beers. Programmers see a genius using binary to order exactly the right amount. In binary, 10 = 2 in decimal, but the guy says "THREE beers" because that's how many nerds showed up to the bar. The bartender's probably thinking, "Great, another group that's going to discuss Big O notation over IPAs." The real tragedy? They'll spend the entire night arguing whether arrays should start at 0 or 1.
