I travelled more than 20 hours from Sydney, Australia to Kerala and did not have a pleasant experience at Kochi airport.
Having forgotten to bring a pen along with me I searched all desks at the immigration area for a pen but in vain. I asked an official and instead of handing me the one in his pocket he directed me all the way across the hall to a desk with a lady sitting behind it. When I asked her for a pen she suggested I go look at the desks and when told that there were no pens there started arguing with me until in frustration I grabbed one from her desk. And when I complained at the immigration desk the officer laughed it off and asked me to carry one in my hand bag.
Waiting times and cleanliness was acceptable but service and attitude of officials was atrocious.
