Milwaukee police say a customer upset with his order at a Taco Bell shot into the restaurant's drive-thru window.
Taco Bell management says that after leaving with his order, the man was upset to discover the employees forgot to add sour cream.
He called the restaurant and the manager told him to come back the next day for a free meal because they were closed.
Authorities say the man returned a short time later, about 12:20 a.m. Monday, and shot at the bullet-proof window and an employee's car.
No one was hurt. Police are looking for the man.
