I was sitting at a table at a tropical-themed outdoor bar with an ex-girlfriend. Someone up at the bar invited me to drink with him. I couldn’t decide what to drink. “A Coke?” the bartender suggested. “What’s in that?” I asked. “Coke,” he replied. I’d imagined it was a whole lot of different booze that tastes like Coke when it’s mixed together. I considered a tequila shot.
