This story and Coherence movie could greatly complement each other,though the latter one offers more thrill and grittiness to the concept.
In this first person narrative, a young man from the countryside shares with readers, his strange experiences at Harry’s all-nighter, where he worked his teenage days off. Harry’s All night Hamburgers could be considered as a Way Station, unlike Simak’s Intergalactic one, this version works on Interdimensional platform. Narrator encounters strange beings, multiple versions of same person and is occasionally seduced by the possibility of being an Interdimensional travel bug.
Most striking fact about this story is, that even in its pompous setting of parallel universes and wanderlust, it is essentially a pleasant travel motivation short. And the feelings I am left with, after the read, goes something like this.
I should make it to Banaras at least this year :).
