It is also difficult to make friends with them. Yes, you will be an acquaintance but a friend rarely. In the German speaking part, they have an odd etiquette of calling someone Herr or Frau until the moment when they 'formally' give you permission to use their first name. One will perhaps not notice this if one speaks English and uses first names from the start - as an American or British person would naturally do. Switzerland is a very safe country and the crime rate is very low.
Gun ownership is very high.
The Swiss are educated to a very high standard and are usually very cultured. In terms of climate, Switzerland is very cold in the winter months and quite hot in the summer. Visitors can use credit cards and cash readily. The Swiss are quite particular about visas so make inquiries before departing. Plan your itinerary, bring plenty of cash and check your visa to make the most of a holiday in Switzerland.
