If you ever wander into a McDonald’s in Australia late at night, you might find yourself listening to classical music while indulging in a Big Mac. No, it’s not a mistake — some locations use the trick to attempt to prevent drunken fights.
According to news.com.au, locations in Scotland and England have also tested the strategy after brawls broke out at the restaurants.
“We have tested the effects of classical music in the past and played it in some of our restaurants as it encourages more acceptable behavior,” a McDonald’s spokesperson told Mirror. “Typically, classical music is played from early evening onwards, and in some cases, on certain nights in a small number of restaurants.”
A McDonald’s Australia spokeswoman said although playing classical music to curb drunk fights isn’t a companywide policy, some locations have tried it in the past.
Why classical music? Studies suggest that playing classical music has a calming effect that can reduce stress and improve sleep patterns. One study conducted by the University of Southern California listening to Bach, Brahms, and Mozart was particularly helpful when studying for finals.
