He found the beef. A Wendy’s customer who flew into a rage when his drive-thru order was wrong unleashed fury and bullets on the fast-food workers he believed messed up his meal, according to local reports. Christian Ellis, 19, went to a Wendy’s location in Frisco, Texas, on Aug. 17, according to the local FOX station. After picking up his food at the drive-thru window, he went inside the store and began arguing with employees about what was in his Biggie Bag.
