"Fàilte! A bheil Gàidhlig agad?"
Translation:Welcome! Do you have Gaelic?
No, it doesn't, and that myth needs to die a fiery death.
Even if you discount its use in Scotland, it's still used by Americans of sufficient age. I have neighbors who have never been out of our State but would say "have Sarah order, she's got a little bit of that Spanish". Literally walk into any Mexican restaurant in rural America and you're guaranteed to hear SOMEBODY say that (with a different name) at some point in the day.
