I didn’t watch the video but I know this - studies have shown that if a store plays “pop” or more often plain ‘ole rock and roll, customers leave sooner whereas if classical music is played, customers tend to linger. It’s not a secret. Why stores don’t play Mozart, Hayden, and Beethoven is beyond me.Except if you're a merchant in Oakland, CA (14th & Broadway) or San Francisco (Market & 8th or thereabouts) and you pipe classical music loudly on the street to drive away the drug dealers and the panhandlers.
