As my taxi approached Nice airport we took a lane that was marked 'Kiss and Fly'. I was worried for a moment that the taxi driver might try to kiss me for a bigger tip, but fortunately he made no attempt to do so (I was keeping my distance though as he was unloading my bags - just to be on the safe side).

I suppose the 'Kiss and Fly' label is a tourist-friendly way of saying 'No waiting'. I thought it was a nice touch.
