Social experiment: they asked for food on the street
Imagine that a complete stranger in the street to ask you to share with them a meal. What would be your reaction? These guys decided to conduct a social experiment and learn how people react to such a request. They approached the bystanders who snack on the street and asked to treat them with food. People come up with various excuses and refused guys. But when they came up with the same request to the homeless, the one without a second's hesitation, shared with them the pizza.
It is unbelievable that a man who himself asks for help from other people willing to share the last piece of pizza with random passers-by! Would you share a meal with a stranger?
