What cultural faux pas should I try to avoid making in Liechtenstein?

"It is important to be aware of the cultural norms in Liechtenstein and to respect them. It is considered rude to be late for appointments or social engagements, so it is important to be punctual. It is also important to dress appropriately for the occasion, as Liechtensteiners take pride in their appearance. It is also important to be aware of the local customs and to show respect for them. It is also important to be aware of the local language and to make an effort to speak it, as English is not widely spoken in Liechtenstein.
