You must be using the wrong AD if that's the way they treat you. Either that or something causes them to act that way. The AD I use is really nice, the sales people are both pleasant and knowledgable, and try to help even a pauper like me to obtain some of the sought after models. Even sent a watch back under warranty which was borderline whether or not I had caused the fault (crown threads damaged) which Rolex honoured.
Never had to buy a watch I didn't like either. I do wear previous purchases when visiting them so they do know I'm not flipping them which perhaps counts for something.
As for being afraid to wear them, the only place I've ever felt that way is in London, when passing through and staying overnight for an early start on Eurostar. Out for a meal and a couple of crafty pints and the beater comes out until we're boarded the next morning.
