My colleague Harry had bought a present for another colleague who was parting from the team. The rest of the team 'went Dutch' on damage, and had to contribute 5 Euros each (actually, the story is set in the Netherlands, where 'going Dutch' is indeed a popular way of settling financial issues).
One of the team members didn't have the cash at hand, but insisted on settling in cash some later time (instead of transferring). But then, the whole transaction got forgotten and the remainder of the team dissolved.
Weeks later, Harry ran into his debtor on some occassion and reminded him of the 5 outstanding Euros. Again the former team member insisted on settling in cash, which again, he didn't have at hand - "Just give me your address and I'll mail you the money".
A few days later, to his utmost amazement, Harry did not receive an envelope with a 5 Euro note in it, as expected, but a postcard with five coins of one euro attached to the shiny side with self-adhesive tape...
So, if ever you swap to somebody in the Netherlands - don't worry about packaging because our mailmen are dead honest!
Though I don't fancy the self-adhesive tape part of the story...
