Free beer is the sweetest even when you can afford it...

Snail is free in my village. Our custom forbids us from touching let alone eat it. During the rainy season you see a lot of snails in nearby bushes. People come from other towns to come and collect the small tiny snails Even though we know where to find the big snails, we are also forbidden from showing them where to find the big big ones. They claim and believe that snails used to be gentlemen humans in their previous life, so we should let them be.
