Generally comfortable airport, moving between term...

Generally comfortable airport, moving between terminals is easy. But the navigation is sometimes bit confusing, it's not clear how the letters are connected with numbers, and signs A1 B2 C3 for the second time(!) I visit this airport have made false impression that terminal 2 is B instead of D.

Also VAT return instruction should better highlight the fact that the customs are in B, not in international D and should suggest to follow Zoll sign for better understanding.

I'd like to personally thank Herr Sven Schneider who kindly explained me the right procedure of getting VAT return, when I have choosen the wrong order. Thank you very much!
