OKLAHOMA CITY – A man so upset over not receiving the hot sauce he wanted fired several shots through a drive thru window at Taco Bell.

Early Monday morning, the man pulled up to the window at the Oklahoma City drive-thru and yelled at employees that they had forgot his taco sauce.

KOCO reports the man pulled out a semi-automatic handgun and began firing, sending employees into the back of the restaurant where they locked themselves in a bathroom.

The unidentified suspect entered the Taco Bell after firing his gun and left before police arrived.
