I know that there are many tell-tale signs that we're American. I didn't say that there was anything wrong with saying "you're welcome", just that it sounds American.
New-Dawn, if you, speaking as a Brit, like "you're welcome", and you think it would be nice for other Brits to say "you're welcome" that's fine. I just don't think you should criticize other British people for not saying it when, according to the culture they are exposed to, they aren't expected to say it.
Are children in Britain taught to say "you're welcome" when they learn manners from their parents or teachers? If they are, then if they don't say it as adults, they're being lazy. But if they're not taught to say it, how can they, as adults, be criticized for not saying it?
