I live next door to Sri Lankan 'cookers' and every night I 'get the torture'. I'm not sure I would be an afficionado of the eating with the fingers style but wow! Does the food smell good.
I played cricket in Stockholm for a number of years for a Sri Lankan team.
My first match and it came to the 'tea' interval. There were no facilities (i.e. tables, chairs, a room) but I was treated to an hour-long buffet of magnificent Sri Lankan cuisine. Me, not being afraid of getting stuck in, was in a bit of a dilemma, though: there was no cutlery!

I hadn't eaten with my fingers (proper food, not sarnies or the like) since I was a nipper in nappies, and I was about to recreate my dining skills again.
I was shown the three-finger method, but instead of using my thumb to 'shovel' the food in my other two fingers into my mouth, I tried to use all three, with unfortunate results. My cricket shirt and whites were stained horribly with gravy, sauce and almost anything else that slipped through my fingers. They laughed at me, but mostly out of pity.
For the next game, they provided me with a fork and spoon. Although, I must admit that I've become a
dab-hand at eating Asian food with my fingers.
