Customs at JFK airport wanted to charge me per foot of a 2400' tape until I pointed out that it was a used tape not new, and after some searching through their books they couldn't find a rate for used tape and let me take it away. Another time a TV set modified in the UK to pretend to be a colour terminal, which were extraordinarily expensive in 1980, took a long time to get through even with wires hanging out of the back and a British mains plug. As it was in a box that had COLOUR (sic) on every side it was of course stolen the first night it was in the office in New Jersey. Phone call to Stevenage the next day was "Please send another, and a mains transformer too."
