I'm not American so I am probably mistaken, but I thought your first amendment only covered the government taking away your right to free speech. Is that wrong?
Good for you Spooky! I've got several friends that work for Apple at the many Bay Area Apple Stores and they are just like you when it comes to the rules in their employment contract; they totally disagree with many of the stringent and ticky-tack rules they must abide by on a daily basis...
Cheers....many people thought i was crazy for leaving, but I refused to work for a company with terms and conditions (small-print) that Apple had. Don't get me wrong, it was a fun job but there were times where the customer was clearly in the right but the process was set up so Apple could turn them away at every turn. No doubt this was as frustrating for the customer as it was for me. For me it came down to a question of ethics: should I be selling this product to a customer if I don't feel it has the support/quality the advertisements talk about? My answer was no, so I left.
I should note that it was my experience, not the status quo.
