We all know that Valentine’s Day is a heart-filled holiday, but is it possible that seeing a heart changes how much you tip at a restaurant? In a study of over 350 restaurant patrons’, waitresses delivered the bill under one of three candy-filled dishes: square, round, or heart-shaped. Results revealed that more people tipped (the study was in France, where tipping isn’t necessarily automatic) when provided with a heart-shaped dish and tipped a higher amount compared to the other two shapes. If you work as a waiter or waitress, perhaps you can make hearts work for you throughout the year.
