Oh what a rich subject matter..or can of worms we have opened...
Oz immigration, top notch, very very polite, sensible and helpful in the right circumstances.
Oz customs..well, what a bunch of impolite, oxygen stealing, lacking a braincell between them bunch of malevolent A-holes I have had the misfortune to come into contact with. Honestly I wouldn't even bother crossing the street to piss on one of them if they were on fire....
Does the customs exam include a compulsory lobotomy? perhaps they scoop out the stupid ones from the gene pool and send them off to train as a customs officer, and before anyone asks, no I haven't been on the receiving end....YET, but I've seen first hand the application of pedantic rule based behavior that does nothing other than make the customs officials look idiotic, and better yet does nothing to improve compliance or bio-security.
Dumbass is a good descriptive Noun for the whole organization.
