Deputies say the man first fired shots from his car as he drove down the Eastex Freeway because he believed someone was shooting at him.
He then pulled into the restaurant, fired shots at the back door and went inside, deputies said.

HCSO says he then dropped the gun and started throwing food around.
"He appears intoxicated on some sort of drugs," Captain John Sannon said.
Deputies say the restaurant was closed at the time, and only employees were inside.
Photos from the scene show the suspect's weapon laying in shattered glass from the broken door.
No one was seriously hurt, but the man suffered several cuts from the broken glass.
"[The suspect is] being held for mental health and facing weapons charges for shooting," Shannon said. "[It] could have been a lot worse."
