Not sure where to put this so will try here.

Other than Raclette, Fondue, this does not seem to be a very common practice in Swiss (german culture)? I have a couple experiences, one was a meal in Hong Kong with a few Swiss colleagues and Hong Kong colleagues, the Swiss were rather relunctant to take food from common plates.

Likewise, last weekend was eating at a restuarant in Chinatown NYC. There was a family of four German tourists eating at the table next to me. They each order a sweet and sour pork individually. Four orders of the same exact same dish. Having much exposure to Asian culture, this made me laugh internally...this was family not even strangers. And being in the US with US portion size this means they probably were eating sweet sour pork for lunch the next day.
