HOUSTON -- Two people suffered third degree burns after a dispute at a Taco Bell in Houston.
It started when a manager was arguing with a customer about littering in the drive-thru lane.
The customer went inside to report it, and the manager threw a drink at him. He says that's when the manager stabbed him with a butcher knife.
A 17-year-old boy got out of the car to break up the fight, when an employee threw hot grease at him.
He's now in intensive care with burns on over 70 percent of his body.
A woman returned to the Taco Bell later to complain about what happened and had hot grease thrown at her too.
The employees say the woman was throwing rocks and threatening them.
Police are investigating, but so far no one has been charged with a crime.
A spokesman for Taco Bell said in a statement to WGN:
The safety of our employees and customers is our top priority and we are very upset this happened in our restaurant. We are cooperating with the Houston police in their investigation and are in process of filing charges and property damage complaints with them. This was a traumatic incident for our employees and we are supporting them by offering counselling.
