Occurred on May 23, 2013 San Antonio, Texas, USAbr br Info from Licensor: "I was waiting in line at McDonald's Drive-thru late around midnight with my girlfriend. I accidentally bumped my car horn, and the vehicle in front of me honked back. It went back and forth a few times before I turned on my camera on my phone and captured the rest of the honking. This all happened because we thought it was amusing and we were bored from waiting in line. In the end I just put my phone away, accepted my order, and went home.
