What bar doesn’t want to promote their business; business is made on customers buying drinks! But in Brazil, the harsher traffic laws didn’t help decrease drunk drivers, so Blá Bar had an idea to help.
Arrive at the bar, and the valet takes note of who drove there. Then when the first round is served, only the driver received a special mug with funny sayings showing the effects alcohol has on them. The result- most drivers switched over to non-alcoholic drinks, while the ones who didn't received a taxi ride.
