Eating with hands even sound less disgusting dude.I saw the eating fish curry in a such a say that the curry was flowing from their hands to forearms and finally on their lungis and legs.
Lol! Who you been hanging out with? You were probably hanging out with some third class Bangladeshis. If you were a a guest of a real sophisticated bangladeshi guy, he would not be walking out in a Lungi and eating his lunch/dinner in front of you like that in a Lungi, in addition to eating like a savage.
