I just spent some time reading up on social etiquette in Turkey, Germany and Switzerland. To say the very least, I have a lot to remember. Social etiquette doesn´t particularly exist here, in my opinion. If you don´t believe me, google a few countries´ manners and then read this: http://www.associatedcontent.com/article/9889/american_manners_etiquette_and_protocol.html?cat=16. It´s disturbing, hilarious, and generally very true.
