A common scam in Nairobi is that of the "fake tour guide", where people pose as tour guides and offer to take you on a tour. They then take you to places where you have to pay exorbitant fees for entrance, transportation and other expenses. To avoid this, it is best to book tours with reputable companies. Another scam is the "broken meter" scam, where cab drivers claim their meter is broken and then overcharge you. To avoid this, negotiate and agree on the fare before you get into the cab.
