Nearly Almost Dead But Not Quite!

I like to imagine that Nasty Burger is kinda like a more extreme Waffle House in the DP universe. Like Amity Park has a 'Nasty Burger index' where they gauge how bad a ghost problem is based on how the Nasty Burger is operating, it they are functioning normally its just something like Skulker or Ember, if they have a reduced menu some sort of calamity has occured like Pariah Dark invading, and if they're closed it's a lost cause, there is no hope and they are doomed. The only time Nasty Burger has ever closed outside of regular operating hours was when the building blew up in TUE, they were open through the end of Phantom Planet and had no plans of ending operations until the building wasn't standing.

I was mostly joking but recently rewatched most of the series with my sister and they were genuinely open during Reign Storm as if nothing was wrong. They're more powerful than I thought.
