Back in the70s my dad worked or a trucking company that hauled meat like sides of beef etc. They had to go down to the Peace Bridge to transfer a load from a Canadian truck to one of theirs. Thet got it almost done and the customs inspector examines it and sees something wrong with the paperwork. He starts questioning each laborer which took about 2-3 hours, until a boss came to straighten it out. Customs put a seal on the truck with had to be removed by customs in NYC, which is where the load was headed.
