What is going on? Witnessed this at a servo today in Ballajura

Just witnessed something today that I normally only see on the local police Facebook pages.

Stopped at a servo to pay for fuel, and suddenly 4–6 teenagers ran into the shop and started grabbing whatever they could. They were even making a game out of it, trying to see who could take the most stuff from the fridges. It was all happening in broad daylight, and they didn't seem to care that people were watching them stealing

It was just me and another lady in the shop. The attendant managed to chase the teens out and locked the door, but a couple of them kept hanging around outside, still trying to get back in. He asked the two of us to stay inside for a few minutes until they finally left, which I really appreciated.

Big respect to the attendant for putting our safety first. Still can't believe I actually witnessed something like that. Has anyone else seen this sort of thing happening lately?
