Here’s an example of stupidity in usability. On the pickup window of a
local Burger King drive-thru, there is a small sticker that reads,

Please present coupons before ordering.

First of all, shouldn’t the notice be posted at the point of ordering,
rather than at the point of pickup?

Second, shouldn’t the print be much larger?

On top of all that, the sticker is on the outside of the pickup window
which folds out when opened, so the reader can no longer see it.

Of course, when I mentioned all of this (as nicely as I could) to the
person at the window, all she could do was blush, smile, and shrug just as
all helpless, unempowered peons do. The old “Don’t look at me–I just
work here” line applies to this situation.

I’m sure she thought I was either a nut, a jerk, or both.

Ain’t life grand?
