Woman is filmed doing a number two on a public bus

A video uploaded online shows a woman squatting in the middle of a packed public bus and letting her bowels lose. Passengers can be heard expressing their disgust as they film the scene. Despite multiple commuters taking out their phones to record the sickening sight, the woman doesn't appear bothered.
The video's caption suggests the woman was desperate and only squatted in a public as 'a matter of urgency'. The clip is believed to have been taken in Hong Kong.
