“Hit me! Hit me two times! Hit me again! Ok stop.”

No, this is not quite the sadomasochistic dialogue between the punisher and the punished, but rather the “Green means go, red means stop” card signals are for the Gaucho chefs preparing you skewer meat sticks at this Brazilian steakhouse. The more meat you want, the more green you show. Red has the reverse effect so order accordingly. –E.J.
