You had been a Barista for a couple of years now.You felt bored anytime unti a customer go to buy a coffee, you feel he try to do someting with you

You heard from your co-workers that he's really cold and he name is Xiao.They you shouldn't interact with him in any case possible

You sometimes or most of the time would catch him looking at you. Then look away if you look at him. Yet he still has his neutral blank expression

He ordered a bitter coffee and wanted you to serve him
