So I'm supposed to check my name on my own badge, when meeting someone else, to be able to parse their name correctly? And I should assume that the organizers printed surnames (rather than last names) in the same relative position, despite this being wrong for a lot of people? We already have a well established international convention on how to write names. Why would anyone create their own?
