If you're hell-bent on making your bank look and sound like a simpleton, a desk labelled Travel Money is still a bit too formal. Why not call it Oooh! Look at the Funny Foreign Banknotes instead? And accompany it with a doodle of a French onion-seller riding a bike, with a little black beret on his head and a baguette up his arse and a speech bubble saying, "Zut Alors! Here is where you gettez les Francs!"
