The Swiss tend to be proud and reserved, but they can be exceedingly polite and helpful if encountered on their terms. Always greet shop owners and restaurant staff with “Greüzi” (hello) when entering, and “entschuldigen” (pardon) before asking a question or making a request. Use polite tram etiquette. On older trams, avoid the second car, which is reserved for strollers and wheelchairs, unless necessary. If you want to cross ahead of an idle tram, make eye contact with the driver and proceed only if he waves you through. The Swiss are very rule abiding: You’ll find them standing at a red light even if there’s no traffic in sight. Follow their lead.
