Searching the Stalls

A character hides inside a bathroom stall, and to find him, another character enters the bathroom and begins a systematic search of each stall. If it's our protagonist hiding from the villain, then four things may happen (and none of these count as subversions!).
 * The villain gets interrupted before he makes it to the hero's stall.
 * The hero somehow escapes unseen and his stall is revealed to be empty.
 * Less commonly, the hero surprise attacks the villain before his stall is opened.
 * If the villain is Dangerously Genre Savvy and armed with a gun, he'll shoot into each stall, though the hero will likely find a way to avoid getting shot up.

Who is searching for whom varies widely, but it always involves a linear process-of-elimination search of the stalls. Expect a shot at foot-level at some point, and a Scare Chord when the last stall door is flung open. Variations on the basic structure are quite common.

Comic Books

Film

He gets to the last stall and realizes there's a woman inside. He figures Hooker went out the window and does the same. It turns out Hooker was inside the stall with the woman -- she was helping him.
 * In The Warriors, the Punks line up to kick all the stalls open at the same time. The Warriors open the doors first and a brawl ensues.

 * High School Musical used this to show us how Gabriella was able to turn invisible. Seriously: Sharpay hears her singing in the loo, sees nobody, checks out the stalls, kicks the lone closed-yet-vacant stall open, then spies herself in the mirror and leaves. Gabriella then reveals that she was behind the entrance wall (beside the basins). In a place Sharpay looked. True, we don't actually see Gabriella's hiding place (so she could very well have been under the basins), but the way it's played makes us wonder why she doesn't slip out while Sharpay's back was turned.
 * In Air Force One, while he's being pursued by the terrorists through the plane's passenger levels, the President hides in the bathroom section. The terrorists then shoot up each stall, and check each door, only to find they're empty. Turns out the President used a different method to evade them.

Other

Then she kills them.
