A stall is not a failure of the person holding the phone. It is a moment the path asked for something that was not yet in the room: a policy number, a postcode format, a reason for a permission.
We count a stall when the thumbs stop for more than a breath and the face turns toward us, or toward the ceiling. We do not then point at the button. If we point, we have walked the path for them, and the map will lie.
The written audit later can still be kind. Kindness is in the description: “waited, reread the label, opened the menu, returned.” It is not in pretending the button was obvious. Product teams in Malaysia are often polite in the readout. Our job is to keep the stall on the page so politeness does not erase it.
A practical rule: if you feel the urge to help, write the time on your notepad instead. Help after the task is abandoned or finished.
