Bon voyage et bonne chance…some o’ them furriners look nasty.
Make sure to be AMERICAN: laugh at their funny accents, they like that.
Turn your our nose up at their crappy native food and ask for something American, like a hamburger, they like that too.
And tell everyone how you don’t mind people speaking a foreign language instead of English, you just one them to speak ONE foreign language, not the bloody mish-mash you get across Europe. And as for the hoity-toity accents in England, well….
