ATC sometimes gets very testy if you question why you are being given a vector or a change in altitude. Two weekends ago I was given a switch to Oakland Center. After three attempts at contact the controller finally came up and gave me a little wrist slap saying he was on the other line and not to be so impatient. Of course they are often on the 'land line', but my time between contact attempts was not so quick to warrent such a response. On top of that - he actually got his ire up when I asked WHY I was being sent to a certain entry point further to the north and not the usual entry point for landing on Runway 32 at my home base. Well....about 3-5 minutes later I get the redirect to the correct point for my approach to the field. Hey....maybe I was the unwitting pawn in some controller training
