Cell phone video shows the irate man yelling at fast food workers through the drive-thru window.
A worker tries to fend the man off with a boom. That man then climbs through the windows and brawls with the workers.
A male coworker tries to restrain the man as he goes after the two female workers.
The person who uploaded the video put up a caption claiming the fight began over the restaurant chain running out of chicken sandwiches, although it is not clear whether this specific incident was caused by the chain’s nationwide chicken sandwich shortage.
