McDonald’s was skewered on social media by frustrated customers who had hoped to score some of its limited edition Szechuan sauce but were instead turned away and left empty-handed.

The fast-food behemoth behind the McRib, the Shamrock Shake and other cult favorites promised to bring back the same Szechuan sauce that debuted when the Disney film “Mulan” was released in 1998. It was only to be available on Saturday, and only in select stores.

But the lines were long. The sauce was scarce. It was a recipe for disappointment.
