After the host brought you to the table, the captain would hand you menus and ask about your water preference. Moments later, and without any visible communication—often before the captain had even left the table—your server would be at the table, pouring your preferred water choice. It wasn’t magic; the captain had discreetly signaled your preference to one of their colleagues using a hand gesture (wiggled fingers for bubbles, a straight chop for still, and a twist of the fist for ice) behind their back.
