Swiss people are quite cold. I lived in Basel for 2 years and I was glad to leave.
The reason why I left was because the Swiss police (who are notoriously draconian) wrongly accused me of trying to leave the country without settling a £200.00 bill. (I'd paid it the day before I was due to fly out).
The police phoned my employers to complain, without getting any evidence from me that I'd paid the bill. I subsequently sued my employers when they tried to dimiss be for 'gross misconduct'.
See, the Swiss police just don't know how stupid that they really are and yes... I agree that they are very racist.
