Driver was in an Arbys drive-thru flirting with the Arbys girls at the window, we are waiting behind him. Decides to "roll coal" on us, so we honk at him and tell him to stop. Driver them threatens to throw it into reverse and and crash into us, and he seems intoxicated. We then decide its best to leave. As soon as we leave the parking lot, he jets off around the other side of the building intimidating us through the parking lot of the plaza.
