Today's buai pekpek in Port Moresby

Today was a public holiday - National Covenant Day - however, it was just another day in Port Moresby, with the same old buai pekpek (betelnut shit) all over the place.
If we made a covenant today, it should have been for a cleaner Port Moresby and Papua New Guinea.
Happy buai pekpek!
Along Wards Road between Hohola and Waigani

Ubiquitous buai pekpek outside Mobil Service Station, Waigani

How can we ever control these buai vendors like this one outside BSP Waigani?
