Tourists to Sicily can stick it to Cosa Nostra by only spending their dollars with establishments that do not pay off the local goons in a growing movement known as addio pizzo or "goodbye protection money" as reported by Caroline Chaumont for the Global Post:
In Italy, groups like Sicily's Cosa Nostra are destructive as well as economically vexing. Mob operatives routinely extort protection money from businesses, intimidating and inflicting violence on those that don't cooperate. These days, tourists and specialized travel agencies in Southern Italy are fighting back, by supporting business that defy the mafia. * * * "There is a strong demand for [anti-mafia tourism]," said Francesca Vannini Parenti, the founder of Addiopizzo Travel, a Palermo-based agency that offers mafia-free holidays. "People want to know which shops, restaurants and hotels don't pay protection money to the mafia."
It's an economic version of the popular carnival game whack-a-mobster.
