Welcome! (Willkommen! (Bienvenue ! (Benvenuto!))) To Switzerland!

The first time you step over the Swiss border is a uni-linguists' nightmare:

I grabbed my USA Today and headed for the kiosk cashier
"Bonjour," I said. "No...wait..."
"Hallo! Wie kann ich dir helfen? "
"Um..."
"Uno S.U.A. oggi?"
"Um...and a Coca Light."
"Quello sarà 7.40, prego."
I dig through my new assortment of colored bills and decide to pay with the orange one.
"Et 2.60 est votre changement. Merci et avoir une bonne journée !"
"Right...um...yeah thanks."

What the hell.
