Hasn't this been posted here before? I swear I saw it on this forum before.
I think it shows the resilience of a semi-poor people to survive and conduct business in ways we are too prudish to accept. The food is fine, they placed all of it so it doesn't get touched or damaged. We are supposed to wash fruits and veggies before we eat or cook them anyway, right? Imagine the chemicals we get on our mass produced veggies and tell me that isn't as bad or worse.
I find those cultures amazingly engenius with what they can accomplish with so little.
