Does Everyone Else Have an Innate Sense of Direction?

The business world discriminates against me, and I think I know why.

Everywhere I turn there are signs explaining how to find something or other based on cardinal directions:

"Please use the west door."

"The automatic hand dryer is located on the south wall."

The first I can somewhat understand. Outside a building, one can rely on the position of the sun or knowledge of the layout of surrounding streets to determine which way west is. But the second example -- c'mon, I'm inside a freakin' bathroom, for crying out loud! I can't see the streets, and I'm dealing with a place where the sun don't shine, literally and figuratively. Why not tell me the dryer is behind me? (Further, why not say it's hidden behind the bathroom stall door?) Why not say, "Please use the door to your left"?

I'm convinced it's because everyone who didn't have a tummyache on the one day they covered cardinal directions in elementary school wants to maintain their hegemony over me. I should grab a big fat permanent marker to edit all those offending signs hither and yon -- but I might not get the directions right.
