Be careful of who you argue with...in the bus.

Chanced upon this clip....it is about an incident in Hong Kong whereby a young commuter got more than what he bargained for when he told a fellow bus commuter to lower his voice when answering his handphone.

The incident was secretly captured by another fellow bus commuter. View the clip with discretion as foul language in cantonese is used very now and then.

So, in a similar situation, should we just mind our business or we should speak up for our rights?
