A Texas man who ordered his hamburger at Whataburger without onions, only to receive a burger with onions, is now suing the fast food chain after he says he experienced an allergic reaction. Demery Ardell Wilson says the July 2024 incident resulted in "serious personal injuries," and he is suing for an amount between $250,000 and $1 million, USA Today reports. Wilson also has a pending lawsuit against Sonic Drive-In for a nearly identical experience he says he had there in 2023, the Houston Chronicle reports. Both restaurant chains deny the allegations.
