An incident on advertising

So, it was yesterday afternoon at a bus stop and one of the very big network carriers in Nigeria was holding an awareness campaign with plenty students (who are at home for a very long ASUU induced holiday) volunteering to help with the campaign or recruited. They looked beautiful in their yellow T- shirts and black pants as they danced merrily to the music playing from the mobile van and shared the SIM cards to innocent passers by who were rather more interested in getting away from the music and traffic the mobile van was causing. The Dj was really getting the crowd into the grove gradually as he played tune after tune of Nigerian hit songs from back in the day. The Dj was the sound that was selling this particular campaign and he must have for a long minute forgotten who was paying him as he started a hit track by Eldee ft Banky - W. Yeah, big boy and nobody including myself was expecting to hear the lyrics so loud from the speakers as I walked by as Banky's voice on his verse kept on blaring out. Then every one was jolted when Banky innocently said in his verse the name of a rival network provider on the song. The whole bus stop froze as all eyes went to the Dj and those eyes asked with so much venom, "WHAT?". Yeah talk about advertising for a rival brand on a street campaign. Funny enough, a crowd was gathering not too far from this musical jamboree patronizing this said rival network operator devoid of any fan fare and at hearing that song, well, lets say that many of them had a grin boldly inscribed on their faces. Yeah. That's what advertising campaigns can do, right?
