I do like a sign that’s comprehensive, covering all bases. Like this one, which helpfully takes you through all of the possible ways that you could open the door. It’s nice to be given step-by-step instructions, even though you’d think most people could open a door.
The kicker is in the final paragraph, where it turns out that the door doesn’t open at all, and the actual entrance is somewhere else! This feels a bit like a dig at all those people who would rather follow signs than using their common sense.
