Two
monkey waiters are the star attraction at the Kayabukiya tavern, a
traditional “sake house” north of Tokyo, which employed the uniformed
Japanese macaque.
Yat-chan and Fuku-chan serve customers drinks
and hot towels to clean their hands before they order, as per Japanese
custom, and are given soya beans as tips which they get to eat in their
down-time."

"
Both
monkeys are certified by the local authorities, which means that animal
rights regulations regularly visit the premises to ensure the creatures
aren’t being mistreated.
“The monkeys are actually better waiters than some really bad human ones.” said Takayoshi Soeno, a customer at the restaurant."
I'm
sure you've had worse service, be it a teenager who won't put her phone
down or a snooty mayter-dee at some too-fancy-for-you place on the top
floor.
"
Some customers claim that Yat-chan can even understand their exact orders.
“We
called out for more beer just then and it brought us some beer!” said
customer Miho Takikkawa, who came to the tavern specifically to meet
the monkeys."

"
Shoichi Yano, a regular at Kayabukiya’s, says the animals are like her children.
“Actually, [they're] better.” she said. “My son doesn’t listen to me but Yat-chan will.”"

...owner Otsuka is hoping to train another generation of monkey waiters, after receiving three new baby monkeys this year"
