AFAICS. Americans seem to have an inflexible mindset for these sort of things. they don't seem to be able to adapt to local changes to their way of doing things. I see this a lot on Endless-sphere, where they're generally very inflexible when it comes to new things and will just spout out their winning formula, regardless of any requirements that the OP lays down.
This sort of reminds me of an episode years ago, when I had to go to German lessons with an American. The teacher explained that there were many words for "the" in German, so we would start with der, die and das. "Nah" says my American colleague. "That's too complicated, and there's no need for more than one word. I'll just use der. They'll know what I mean".
I wish i could have recorded those German lessons. they were just about the funniest thing that happened to me in my whole life. sometimes, my English colleague came too, and we had to take it in turns to leave the room, run up the corridor and let all the laughter out. One time, I'd just taken a big sip of coffee, while it was the American's turn to answer, but his answer was so funny, that i couldn't help but spit my coffee all over the table. It was really embarrassing, but I just couldn't help it.
