Reminds me of a story my friend told me, who booked a flight from London to Bangkok with Aeroflot, via Moscow. The outgoing flight was delayed so he arrived too late to pick up the Moscow Bangkok one. He went to the transit desk and asked when the next flight would be. "Tuesday", he was told. "But today is Wednesday" he replied.
"Da".
OK, he said, I go visit Moscow while I wait. Where I get worthless Soviet money to spend?
"Nyet", was the stern reply
Sorry No can DO (this was back in the good ole days). No visa, no leave airport. So he spent the next six days living life to the full in Moscow Airport.
True story (so he said).
