Monkeys adopting human behavior! âSake houseâ, a restaurant in Japan, has two monkeys named Yatchan and Fukuchan, working out a two hour shift as waiters. The owner (Kaoru Otsuka) makes them work only for two hours because of animal rights regulations. Perhaps, this is an effective step especially when the global economy is on a decline. Being tipped with boiled soya-beans and that too for a two hour shift is what I call ‘effective negotiation’! Check out the video after the jump.
