Relax over a bud?? You must be crazy !
...steer clear of the "Domestic" variety of American beers if you know whats good for you! Incidentally I was refused a packet of cigarettes in California becasue I didn't have ID....I was 30 ![maybe it was becasue I asked for a packet of fags???].....And my Mrs was refused a bottle of Vodka in Vons because it "was not the companies policy to take a [American] passport as proof of ID"...she was 26....work that one out !
By the way, you DO need a BFR even if issued with an FAA pilots certificate IOBO ICAO L. Its in the FARs somewhere, if you trawl through you should come across it. Also try the FAQs on the FAA website, which are a really good source of plain english Q&As.
