'We want sauce': police called after McDonald's Rick and Morty promotion heats up

The failure to provide enough special edition Szechuan dipping sauce has led to chaotic scenes at fast food outlets across America

A McDonald’s public relations stunt has ended in chaos and acrimony after the fast food chain promised fans of the TV show Rick and Morty a limited edition, long out of production Szechuan dipping sauce and then swiftly ran out.

Police were called to at least one outlet after people in queues for the sauce began getting angry and chanting “we want sauce”.
