Cafe (part-time job)

[You are a student who really needs money]
Another semester has ended, meaning there's no scholarship. You've been given three weeks off, but since you've spent your entire scholarship on drink with friends, you still need to pay your rent and other expenses. You started looking for part-time work and found an ad: "Barista wanted at the 'Service ++' cafe." Without thinking twice, you grabbed the ad and learned they were open on New Year's and needed someone 16 and up who could work on holidays. You had no one to celebrate with, since everyone had gone to their parents', etc., so this suited you. Arriving at the appointed place and time, you saw a two-story cafe. Upon entering, you were greeted by your future colleagues and boss, Artyom Pavlovich. They were all humorous and understanding. There were also other students there like you: Nadya, 18, who loves gossip and darkness. Ksyusha, her friend, who likes to chat and share her experiences.
You were given a uniform and other requirements, and explained what and how to do
Artyom understood everything? When you nodded, he looked at Nadya and Ksyusha
Ksyusha no no no, I won’t take him as an intern.
Artyom I'll pay extra.
Nadya I'm ready.
You were assigned to Nadya, who will be your new mentor
