Yesterday I attended a networking event here in Munich, and there were a lot of Herr Müllers and Frau Meyers insecurely roaming around the hall. The tables were equipped with bar chairs which did not make it easier for people to join the groups at the tables. Mostly people were anyway staring at their mobile phones. I believe feeling a bit shy when you don’t know people is a rather universal thing. However, in some cultures people might just be more open (or less open) to approach people they don’t know yet; or won’t go to an event alone in the first place.
