Well if there's exactly no reason to choose a direction other than the destination of the haunted house, then it is indeed meaningless and shouldn't be offered.Because it is a location. And by making it come up no matter what direction they decide to go, even if their decision is effectively randomly choosing, it means it doesn't matter which direction they go: they will always encounter the haunted house. Also by letting the players pick a direction but then secretly deciding that direction always leads to X, you are creating the impression that the players have a choice, while they in fact do not. If I am in a game like that, and the GM isn't being transparent about this, and it becomes clear to me that my decisions about which direction we go never mattered, it is going to be bother me because I am going to feel like I am being railroaded.
But it seems an unnatural situation. Presumably if the players are choosing a direction it's because they want to go to a certain specific place that they do know about.
In which case the Haunted House, is an encounter on the road, and I fail to see how the fact that it is a place, rather than say a monster, is significant. (In fact, it would seem to offer a meaningful choice that a badly done monster encounter wouldn't. The players can presumably find the haunted house and decide not to enter it?).
