In the Colombian city of Monterrey, in the territory of the Multidisciplinary Institute of technical education, lives in a stray dog named Negro. Universal favorite that is freely running around campus, constantly fed by teachers and students. They often buy her cookies and other Goodies at a local store. But the dog, no wonder rotating in the “scientists” have found a way independently to support themselves.
According to the newspaper Metro, the Negro saw, how people pay, buying food. And “invented” its own currency — the leaves of the trees.
“One day he suddenly appeared with a leaf in its mouth, waving his tail and making it clear that he wants cookies,” — said teacher Angela Garcia Bernal. The saleswoman was so shocked wit Negro that had no choice but to “sell” him a biscuit.
“Now he comes in every day. Always pays and leaves. This is his daily shopping,” says the clerk Gladys Barreto.
The only store employees had limited the purchasing ability of the dog two cookies a day, giving him to understand that this is enough.
