Well, in Japan - the land of singular first and family names - I can rarely get all my names, 4 in all, on my bank books.

Would hardly be a problem, save that when they ask me for other ID they return after closeted discussions stating that my name doesn't match the bank account. The lack of sufficient spaces for my full name is mentioned, and after another closeted discussion they return to say that they need more ID. Then I get annoyed and they go and sort out the problem.
