Flash your cash
You’ve already heard of flash mobbing, the craze that started way back in 2003 in Manhattan. People used social media to arrange to meet in a certain place and join in with an activity like dancing or pillow fighting.
Well, things have taken a more useful turn in the form of cash mobbing. Now people decide to meet at a local store to each spend a small amount of money. The crowd get to socialise, the store gets much needed support.
