I finish my smoke, drink my beer, read the last page of the chapter on Luxembourg in Arthur Frommer's "Europe on 5 Dollars a Day" (trust me, it’s not that long) and wave to the waitress for the bill. I give her the 50 centimes for the beer with the money I had just exchanged from the currency counter next door, hoist my pack on my back and attempt to locate the next bus into Luxembourg City.
