Russian workers are going through smile training ahead of the FIFA World Cup to greet tourists. The games officially begin this Thursday, June 14, with 1.5 million expected tourists.

According to the BBC, Russians don’t really smile as much as other Europeans. They even have a proverb that loosely translates to “Laughing for no reason is a sign of stupidity.”
