Immigration officials across the world are all sent to this common, secret school (run, I suspect by particularly virulent commissars of the ex-USSR) where they are taught the essential niceties of their job – a deeply suspicious look & the ability to never ever let the slightest smile (or even a suspicion thereof) escape on to one’s face, being the most important.
Two countries I have visited stand apart in this – Cyprus & Thailand.
The gate-keepers at the Larnaca airport smiled at me (giving me the heebeejeebies, since to the best of my prior knowledge these guys smile only when about to effect a cop) and – I kid you not – asked about the weather back home.
The guys at Phuket were the best of the lot. Their interaction was as between mature adults. A smile breaking out of a ‘yeah, we know you are here only to have a good time and as soon as your money runs out, you will go away – but we gotta do this…’ look.
I have been to Saudi Arabia too, where I met the guys who took all the prizes at the commissar’s school.
