Around 76' or 77', the company I was driving for had at least a dozen dump trailers hauling deep mined salt off the docks at Port Newark, NJ to several municipalities around north jersey, NYC, out on the island, etc. for highway use.
Anyone who has ever made deliveries in this area might agee with me that as a truck driver, you seem to have to deal with an extrordinarily large number of people that act like they had a rather bad dish of wheaties for breakfast.
Often as not, the high sides of the trailer offered the most privacy for taking care of business. One day, one of the guys took a dump in his dump.
The guy recieving the loads at his next stop was particularly crabby about getting an occasional lump or two in the loads. The bills signed, this guy then runs over and grabs this apparent lump of salt that had rolled to the base of the pile....
