Just a little story from my airline past, we laid over in a city in a country where they take security Very seriously, I was working for a very fine outfit who also took their responsobility for crew safety seriously, in fact the only folks suposed to know our hotel were our diplomatic staff, crew sked supivisors and flight ops management, however on one ocasion I spent a fair bit of money in the local market buying some musical instruments for the kids, on returning to my room I recieved a phone call, it was Visa Canada confirming that I had indeed spent the money! So much for security!
