At a Midwest Strip Mall
Could be a strip mall in the middle of nowhere. Somewhere on the overlay from the plains, the rust belt and the bible belt.
A drug store, a couple clothing boutiques, A party store, sporting goods, antiques, a seedy little adult shop unattached, built right next door--and a second hand clothing store.
Maybe it's some kind of cosmic ray shower. Something about a radio disturbance in space that’s messing up cell signals and making the tech freak out.
But it's more than that--because it's not just the tech that's freaking out.
