New research reinforces the notion that happiness is contagious;
“happiness isn’t just an individual phenomenon; we can catch happiness from friends and family members like an emotional virus. When just one person in a group becomes happy, researchers were able to measure a three-degree spread of that person’s cheer. In other words, our moods can brighten thanks to someone we haven’t even met.”
When a guest walks into your restaurant they are immediately uplifted by the existing energy in the space. Clearly you need to keep them happy.
