Mine was very chatty too, with some juicy gossip to boot. Made me more interested in the conversation than the driving! After the test, my instructor told me this examiner was known for stopping the test if someone made a serious fault and walking back to the test centre rather than be driven back. Not your laid back chatty kind of guy, apparently! I put it down to me being older (I felt, at 46, like grandma in the waiting room).
