Listen man, with these pay raises they should do some better training on their floor staff. I think sometimes they act like they're being nice, but they can come off as rude and condescending. I reached a point that when I need to buy something at an Apple Store, I walk through the door as quick as possible to reduce any interaction with these employees.
Generally, when they speak they are almost looking down on you as if you don't know anything, and they know everything. I always end up correcting them. Example: I asked if they would carry the new Retina MacBook Pros with 16GB of RAM since it's soldered. She said maybe, but you can always buy an 8GB MacBook Pro Retina and we can upgrade it later. I said, but the RAM is soldered, are you sure you're gonna upgrade that? She's like, oh you're right.
This constantly happens. I'm always happy to help my friends when they ask me to come with them to buy a new Mac, because they try to sell them on the AppleCare and other crap they don't need, and typical consumers will not know they have a year to purchase it on most Apple devices. They won't tell you that a lot of times. Very rare I've had an Apple floor staff member be original and nice.
Also, the whole you better be there 15min before your Genius appointment, and they make you wait 45min. If you come 5min late, they cancel you, and ask you to come back another time or sit and wait for 2 hours with a no-care attitude. I've had bad luck with a lot of Apple products over the years, so I got plenty of stories to tell, it's ridiculous.
