happened to me once, i was working at a place in shipping/receiving
we had 16 docks
i was standing in between dock 11 and 12 chatting with someone as one of my hi-lo drivers was unloading the truck parked at dock 12
well, the guy i was chatting with had to leave, so i moved over one spot, and stopped in between dock 12 and 13
i guess my hi lo driver didnt pay attention and used me as a reference point instead of looking at the dock he was unloading and he pulled right into the truck at dock 13...which was just pulling out
the dock plate was allready off and as soon as he got in, the trailer took off
scared the snot out of him, but it he'd been 20 seconds later, hed ended up on the floor outside
