You can learn (basic) coffee knowledge, latte art, and pour-over brewing. Suitable work for part-time employment.

The year-end bonus is laughable. You’ll be exhausted if you encounter a bad store manager. The pay is low. The popular training courses organized by the company are basically out of reach. If you want to learn latte art or pour-over brewing, there’s hardly anyone who can teach you—you can only learn by watching YouTube.
