If you look closely, there are actually a lot of fire exits all over the place, although typically a bit off the path, normally behind those more open exhibits like the room full couches or beds. From the outside they're more obvious, as there are often quite a few fire escape stairs running down the side of the omnipresent blue monolith. Presumably they would be thrown open and employees would direct customers to the ones not immediately obvious.
You'd expect (and hope) they have some pretty rigorous fire safety preparations, considering it's a store full of 95% wood and fabric.
It never happened. It was a joke started on a Spanish, Onion-like comedy site, that went viral in 2018, so definitely nothing to do with social distancing. I wish it were true, because we all love a clever prank, but alas.
