Where I live the addicts used to chase the FedEx truck each morning when it came over the bridge. Whenever the truck stopped the junkies would mob the driver demanding that he check his manifest to see if he had their delivery. FedEx, at least temporarily, stopped delivering packages for several of these shady pharmacies. This was four or five years ago.
And that’s what probably opened the door for this harassment, even though there was no proof that the shippers were still shipping the shady goods.
No good deed goes unpunished it seems.
