My friend who does Bolt told me how he picked up two guys for a trip somewhere in Ibadan. Just as the car moved, the one at the back spoke in Hausa while the one in front responded in Yoruba then the one in front pleaded to smoke while insisting that the windows must be wind up. My friend insisted at first but then agreed when he assured him that it was ‘smokeless.’ The guy lit up the stuff & smoked. After a while, my friend’s eyes became discomforting for him and immediately parked and requested to end the trip. These guys pleaded and offered extra tip.
