I guess I just don't understand how or why as shipper would take the time to ship something to somebody that doesn't want and/or need it.
In all my years of delivery driving, this was a first for me.
That happens more often than you would expect. Just a couple weeks ago, we brought a shipment in that the shipper was in a big hurry to get out and the consignee was frustrated because he already had a warehouse full of the stuff. This was for a big company and the people who receive the stuff are not the ones who order it.
Once it happened that on a long Thanksgiving weekend, we deadheaded from Oregon, I think it was, to Arizona to pick up one small canister of compressed gas to be driven straight through to PA. At the delivery, no one knew it was coming and when they finally figured out what to do with it, we dropped it off in an outdoor yeard containing hundreds if not thousands of gas containers, and dozens of containers exactly like the one we delivered.
Another time, we picked up a load of janitorial supplies after hours at a warehouse and delivered them across town to a restaurant/bar in the middle of their very busy Friday evening. No one at the restaurant knew anything about it but they took the delivery assuming someone at their corporate headquarters ordered it for them.
