Seeing this taxi driver in Paris using 6, yes S I X navigation devices, I had to ask why he utilizes all those gedgets - the answer, short and simple: "It is my job."
At this airport the user needs were not understood. People didn´t need telephones (what the picture does´t show: there were 10 telephones in a row nobody used) they might need electric sockets near a seat.
All you see is a ramp going up (right side) and two stairs going up, but the signs are trying you to convince to go downstairs. This looks a little bit like an A/B Test: "Are five arrows pointing down more convincing, or will eleven arrows pointing left do the job?"
