Recently, McDonald's announced that their Szechuan sauce, which was an exclusive item for a short time in 1998 to promote the film Mulan, would be making a return. After cartoon show Rick and Morty campaigned for its return, McDonald's promised it would return for a single day on October 7.
That day has now passed, but it will be remembered forever as an utter disaster. Stores were reportedly under stocked on the sauce, and the promotional posters that came with them. At popular stores, cops had to be called to keep the peace.
