Recently I was at Thambo International Airport. At the exit of the parking lot I saw a sign that read "Spiked Barrier Wait for Green Robot". At first I paid little attention, then I did a double take, after replaying it in my head I relised that waiting for a green robot is quite a normal for South Africans because a traffic light here is referred to as a robot. Essentially the sign means, "There are spikes on the road, when the light's green it's safe to drive" I can only imagine what some foreigners fresh off the plane must think when they see the sign... 
Asking people to wait for the Green Robot is an example of insensitive planning and design. An international airport serves a very mixed client base and they should implement the most generic and simple English. In an age of information where we understand things as never before I cant help but feel that we are left waiting for the Green Robot too often.
