Fans call for McDonald's 'boycott' following Szechuan sauce snafu

(FOX NEWS) - McDonald's is receiving major backlash after a failed attempt at bringing back a cult-favorite sauce.

As previously reported, McDonald's had agreed to bring back the discontinued Szechuan sauce following pleas from Cartoon Network's adult cartoon, "Rick and Morty."

McDonald's announced last week that for one-day only, the fast food restaurant would carry the Szechuan sauce for customers at participating locations. Thousands of people lined up hours before the packets were allowed to be sold, all clamoring for the sweet plum sauce.

However, McDonald's failed to mention in any of their widespread promos that only 20 packets of the highly anticipated sauce would be available at the stores. The Huffington Post reported that some locations listed online as participating stores didn't actually have the sauce packets at all or some had sold out before the authorized selling time.
