Some times at the 7-11 at campus there are alot of staff there...

4 people behind the desk...

And another person working in the stoff filling the shelves...
But barely any customers...

However...yesterday at 7-11 there were only 2 people in the staff there...but many customers...
I wonder who is responsible for the personnel administration at 7-11...
