Taxi drivers from Orange Farm in the south of Johannesburg met officials from the Gauteng community safety department at the Orange Farm Taxi rank.
"Traffic cops stop us almost every day and demand to see operating permits, and they know most of us don't have permits and then ask for 'cooldrink money'," said taxi driver Mandla Danisi.
Community safety spokesperson Thapelo Moiloa said taxi drivers should refuse and take the names of the officers and their vehicle registration numbers and report them.
