Since botellón is usually a nighttime activity, Spain passed a law that prohibits stores to sell alcohol to the public after 10:00 p.m, hoping to persuade people to attend clubs or bars where alcohol must remain on site. However, the measure is a controversial one because people can still buy alcohol before the selling limit hour and consume it in public. Furthermore, the enforcement of the law is strongest in the most populated botellón areas and has caused some stores away from these enforcement areas to sell alcohol illegally after the limit hour, although they risk fines.
