I would sort, check, organize all the products, manage the cash register for the rest of the shift.
I learned accounting, treating customers, cleaning, sorting out garbage and generally store management.
Retail management service is very big in Korea, I'm not exaggerating when I say probably over 60% of people in my age group would be working in the field currently. There were some predicaments with drunk customers flowing in but other than that it was very relaxing and easy job to have once you're accustomed to it.
The hardest part of the job would be dealing with drunk customers and since it was a 10 hour night shift it was pretty exhausting.
The most enjoyable part of the job was that it was mostly very quiet and relaxing throughout the shift since it was after midnight and I would have a plenty of time for myself once I'm done with all the task for the day.
