Driver was in the parking lot for about 20 minutes, maybe more. But was agitated and banging things around and yelling at someone. I couldn't see that far because this happened at about 8:00pm Tuesday night. After the yelling and loud noise it was quite for about 5-10 minutes. Then The DHL truck Burned and squeaked its tires as it sped out of the parking lot of the business suites ( I work in one), next a white station wagon followed the truck speeding out. However, the truck was driving a lot faster than the following white car. It swayed from side to side and almost landed in a ditch as it made a right out of the parking lot followed but the white vehicle but the white car made a left. The parking lot is pretty much empty and packages are never dleivered this late especially at an office suite because noone is here. It was just weird.
