A Texas man is suing Whataburger after he requested no onions with his meal but got them anyway, according to a court filing.
The lawsuit was filed last month by Demery Wilson in Texas’ 269th Judicial District Court of Harris County.
The documents claim that Wilson visited a Whataburger location on July 24, 2024, and ordered a “fast-food meal” without onions, according to a copy of the filings seen by Fox News. Â

However, Wilson claims that the order did contain onions — which apparently then triggered an “allergic reaction” for which “he had to seek the care of medical professionals.”
Whataburger denied Wilson’s allegations in a separate court document filed on May 16, demanding “strict proof” of his assertions.Â

A representative for the San Antonio, Texas-based fast-food chain told Fox News Digital on Tuesday that the company does not comment on pending litigation.

Although the court filing doesn’t specify what Wilson claims to have ordered from the fast-food chain, the classic Whataburger features a beef patty with mustard, tomato, lettuce, pickles and diced onions on a bun, according to its website.

The Whataburger website also has a page that lists possible allergens, including wheat, soy, gluten, eggs and milk – but not onions.
