Here are a few facts about Liechenstein that I found on the net, we may need them after the invasion:-
Greetings

It's customary to shake hands upon meeting. Always remove gloves first before extending your hand.
When addressing someone, use a title with a last name. First names are usually reserved for young people and the locals.
Gestures

It's inappropriate to talk with hands in your pocket.
Pointing at your head with the index finger is considered an insult.
When dining, it's impolite to leave food on your plate. Asking for seconds compliments the host.
Protocol

Punctuality is important.
Dress neatly and well. European fashions will probably make the best impression.
Be warm but direct. Never give information that can't be backed up factually.
