It’s a legal requirement to smile at all times except at funerals or hospitals in Milan, Italy
What’s with the long face? In Milan, the law compels you to smile. It’s prescribed by a city regulation from Austro-Hungarian times that was never repealed. Exemptions included funeral goers, hospital workers or those at the bedside of an ill family member. For everybody else there is no excuse for being glum, the alternative being a fine.
