I read the news recently of a conductor being kicked from a coaster bus, after he asked a man for his fare. Then he was hit by a passing vehicle and died as a result.
This is brutual and it seems like the same behaviour some men have on the government-owned buses. When they beg a ride or refuse to pay the fare, naturally it is met with opposition from the conductor or the driver. Then the person not paying gets vicious.
The government needs to use cards to collect fares and also have the police check on what's happening in the public transport system.
