This airport beats out even other third world airports I've been to. Forget the construction, the poor infrastructure, the lack of amenities, a pathetic lounge, forget about all that and you're still left with the steaming pile of horse sh*t that is Nikola Tesla Airport, Belgrade. This is a feat that can be fully attributed to the staff at the airport. They are the most self-important, callous, condescending, ill-mannered bunch of people I have ever had the misfortune of coming across. They are so lazy and reluctant to actually do their jobs, choosing to waste every travelers time instead. I have always heard that Serbs were a lazy bunch but this airport takes it to another level.
