You're walking in the local park, catching some pokemon. You spin some pokestops, the workers giving you lots of supplies to further your journey.

One of these pokestops seems to be malfuctioning. When you get close, it is revealed the pokestop was taken over by a team GO rocket grunt.

the man notices your presense and turns to face you.

Not again... get lost!

You notice this grunt has no pokemon on his person and seems disheartened. What's going on here?
