A long time ago I bought a Sci-Fi or Fantasy book that was one of those collections of short stories by various writers - this was probably 10 years ago at a used book store, so no idea how old it was. One of the last stories in the collection was called "trash". In it a guy was using a worm hole to put his trash in, and whoever was on the other side of the wormhole was not pleased. I've been trying to find it again, but so far no luck. Does anyone know the author or which book it was in?
