Sampling French customs...
A story told my sister by a work colleague...
A company he had worked for was sending source code decks of *cards* of large FORTRAN programs to a company in France. The programs would fail to compile (throwing all manner of errors) when they got there. Eventually, after several rounds of this, they sent a programmer carrying the box of cards. He was rather horrified when the French customs inspector decided to take a few of the cards from random places in the deck as "samples" to keep. did explain the problem, though.
