Now, those gas lines, if someone would come around and have a big coffee urn, and offer people coffee while waiting, people get sociable. Instead of maybe, punching or pulling a gun on someone, they might talk and become social. Ever see those on the interstates at the truck stops? This won't last forever, things will get better there, but, in the meantime, maybe, the owners of the stations could offer free drinks/and take donations for the coffee.
A simple cup of coffee, or a bottle of water, can defuse a situation and perhaps, save a life otherwise, when, someone flips out standing there when someone jumps in front of him.
Small things really matter.
