Forget to Say “Please”
Most Swiss in tourist regions speak good English, and are too polite at times when they do so. When starting a conversation in English with the Swiss, always begin with the word “Please.” especially if you have a question to ask.
For example:
“Please, could you tell me where the nearest inn is?” or “Please, may I speak with you in English?” The second sentence may seem inappropriate to you but is desirable and considered good manners when talking with a local.
