Outrageous! The fact that any of the so-called Apple geniuses would raise their voice to you, most especially when this is a genuine problem that Apple has internally already admitted. Take it up the foodchain and call AppleCare. And don't take any kind of "No" for an answer. Every single time I've called them about this issue as well as others (one iPad-related problem),I have only ever had an extremely positive experience! Don't let one store employee ruin the Apple experience for you. Nobody working for Apple is allowed to raise their voice to you and besides, whatever happened to "The customer is always right!".
See this long, long thread on the problem - https://discussions.apple.com/thread/4034848?start=0&tstart=0.
Apple has had no problem replacing screens for others - time and time again.
You had a horrible experience. Go to the manager. Do, as suggested, and call AppleCare as well as Apple Customer Relations.
You should not be stuck with a defective screen.
