Who does not like bargains? I think most of do. So when someone sets up a vending machine selling shirts for 2 Euros (2.25 dollars US), many people flock to it with the goal of buying one. This machine, however, was set up to send out a message which these buyers did not expect to see. After watching the message, many of the would-be buyers change their mind and end up donating their money instead. You would probably do the same thing. Watch the video and see what they witness.
