As an expat living in the U.S., you can either get with local dining culture or stick rigidly to your British ideas about restaurant etiquette.
Wealthy folk in the U.S. and back home in Blighty are a complicated bunch with a rich history and, no doubt, a loaded future.
Although it’s not quite as rigid as keeping to the right on the London Underground, and you won’t provoke the same rage if you err, there actually is a loose system when walking around in the U.S.
Brits may claim that their accents haven’t changed, mine hasn’t after more than twenty years here (see what I mean?) but there’s no doubt that, after a while, Americanisms seep in all the same.
As Brits in the U.S. very quickly discover, not only are there many differences between American and British English, but customs and etiquette “rules” can also deliver a few curve balls.
When you emigrate, your friends go from being fleshy companions whose physical company you quite like to modern-day pen pals. Binary buddies, if you will. Suddenly, your relationships live on your laptop.
