...You must be from Zagreb, as it would surprise me if anyone in the rest of Croatia has ever read the Hitchhiker's Guide. ... 
Er, you got me thinking :-)
Let me try to explain, this is small country where Magic is Big, and Magicians are numerous.
Greatest Magicians are in Zagreb, they are well organized, and work relentlessly to entertain us, so the whole country is highly influenced by them. They are so great and know many tricks, for example:
1) They can do Public Money Disappear trick so efficiently that
even their associates knows nothing about.
2) They can speak for hours and if you try to make a sentence of what they are talking about
you see that sentence disappear.
3) Very popular trick among their local branches is Address Change,
you woke up in the morning and find that the name of your street has been changed, overnight.
That is great, we can replace old boring documents with new ones.
Doing that, we have to walk around for weeks (and walking is good for health)
and actually meet people (so we are not alienated) which we pay by our tax payers money.
That also opens new jobs, not only in Paper branches, Rescue branches are needed too -
to rescue lost postmans and reporters (ah, those poor souls are lost due to 3. while being around researching Mystery of 1.).
We are all Hypnotized by their Greatness:
I'm not exception.
Land Of Magic, I tell you.
