Needless to say, I gave that girl a nice tip. The next morning we left St. Moritz on a train which crossed the Alps to Tirano, Italy. There we had lunch at an outdoor restaurant. Real Italian Pizza. We also had a glass of red wine.
Wine is cheaper there than soft drinks.
However, I sure missed cold water. We never saw a drinking fountain any place in Switzerland. Some restaurants served you water if you asked, but some even charged you for it. Every evening when I reached our hotel, the first thing I would do was drink about 4 glasses of tap water. Not very cold, but it surely hit the spot.
