A man brings a very pretty girl to a jewellery shop. He asks for the best necklace in stock. After rejecting all the cheaper items, he settles on a US$1.000.000 ruby necklace.
"Wrap it for her, - he orders, - And bill my bank next week".
The shop manager is confused. "I'm sorry, we can only deliver the necklace when the bill is honored," - he says apologetically.
"Weird customs you've got here, - the man shrugs, - are you sure it can't be done sooner?!"
"Absolutely, sir", - says the manager, ashamed of himself.
"OK, then get the girl's address and deliver the necklace to her the very moment you've got the clearance."

Early next week the shop manager makes a call to the man.
"I'm sorry, sir, but your bank rejected payment!"
"That's OK, - says the man, I still had a fantastic weekend..."
