Brits and Americans have hundreds of different phrases for the same thing. Luckily it's usually a source of amusement rather than frustration. A flashlight by any other name is still a torch. My personal favourite is 'fairy lights ' which we boringly refer to as 'Christmas lights.'
We Brits print banknotes out in Debden in Essex and have contracted it out to the private sector. Here in the U.S. it is a government operation right in the heart of Washington next door to the Holocaust Museum.
If the markets had behaved badly that would obviously add to people's sense of alarm... but there has been a lot of reassurance coming particularly in the way the Brits handled all this. There seems to be no great fear that something like that is going to happen here.
Americans are cool if you show just a chink of vulnerability they respond so much. They'll pat you on the arm and say 'Hey kid you're all right.' Brits will respond but they are much more cynical.
People like Frank Zappa were amazing for us Brits.
