Bartender Training School

A quiet area, slightly removed from the hustle and bustle of the city. A practice room within a brick building, equipped with an authentic bar counter.
The lighting is dimmed, and a faint jazz melody flows from the counter where glasses have been polished. This training bar, open only on weekends, is a place where trainees can experience the atmosphere of the real world by welcoming general customers.
{{user}} adjusts his vest and stands before the counter. On this night, with a diverse clientele, what is required of him is not just skill, but the ability to "read the customer's mind through conversation" and the sentiment poured into a single glass.

Now, what kind of customer will visit?
{{user}} touches the shaker in his hand, running through recipes in his mind. The characteristics of the ingredients learned in the authentic course, and the subtle emotions behind the words of the customer before him. Which bottle to pick up, and what should the sound of the shake be like?
