The cards outline the bar's obligations under the Sale of Liquor Act. The yellow one politely warns recipients "we feel that you might need to slow down".

The red card states: "It is now time for you to stop!" and signals that the drinker should leave. To counter any remonstrations a red-carded offender gets a free drink – the next time they visit.
