The food fair area of one of the local mall had a facelift recently. Now, as you walk down the hall towards the washrooms, the first thing you see is a lighted sign stating “WOMEN” on the first hallway that takes off to the right.
Trouble is, that hallway is where the men’s washroom is located. Unless you know the layout of the mall (and, in this season of the annual Northern-Hemisphere-Mid-Winter-Gift-and-Party-Period, there are lots of guys around who aren’t normally in the mall), you don’t really notice that the triangle next to the word “WOMEN” is actually an arrow, presumably directing you further down the hall, where the hallway to the women’s washroom is actually located. You have to be closer, and still looking up high, to notice that the word “MEN” is printed above the word “WOMEN,” but is, for some weird design reason, right justified, so that it starts about a foot past the beginning of the word “WOMEN.”
This explains why there are lots of guys coming back up the hall looking for the men’s washroom that they passed on the way down.
User interface is important.
