Kris didn't really think much of Tao, he was just a teenager who came in every once and a while to buy a sandwich or snack, saying hello to one of the noonas and tripping over his own feet. He'd crash into one of the servers and knock over all of the food, making Taeyeon furious and she'd throw her apron up in the air and try to strangle the kid with her bare hands. 

 Okay, so Kris did find Huang Zitao quite annoying. He was always hyper when he was ordering, and Kris would always find one of his hands massaging his temple and the other one punching in Tao's order. He gave him a headache and it wasn't very pleasant. 

 So when the old boss decided to go and hire the kid, Kris didn't know what to think. All he knew was that his life was over.
