I think it would go like this for me.
In this case it looks like I would have gotten a few refills and waited to see what all those cops were doing outside, there must be something really crazy happening next door.
The cops didn't find any BG, who knows if there even was one to deal with. For all we know some snot nosed kid got tired of working and didn't want to make frys anymore and called in a bogus story just to close the store.
Stranger things have happened, well maybe not.
