I have no idea what the laws are in Ecuador when it comes to happy hour and bar opening hours, but if the clients in this bar played their QR coded cards right, they could keep the joint open for 24/7 binge drinking.

Hmm. See, on each coaster given with a Budweiser, there's a QR code. If you scan the coaster at a "budclock" in the bar, you add another minute to happy hour. There. I just saved you one minute of case study watching.

At least the QR-code wasn't a link to a website, right?
