Doorways are convenient. People look up when someone enters, and she seems to know exactly how long that window lasts.

Right at the threshold, something suddenly needs attention. Strap. earring. phone. friend behind her. The delay is small enough to deny, too quick to call posing, but long enough for the bar, host stand, or next table to take her in.

Once is nothing. Twice could be timing. By the third doorway, it has a little routine to it: stop, adjust, let the room catch up, then move like nothing happened.
