It's an apple store and as other have said, it's hit or miss on service. You either have a long wait to be seen at the genius bar or you are taken right away. Today I was in to support my husband making a purchasing decision for computer stuff. There have been times I've gone in and needed help and you would have thought I had a disease or something. Today it seems that they were well staffed and we got there and were helped right away.
It really is the nature of the business, the scheduling in any business can be hit or miss because you can't predict when someone will be in your store.
One thing I will always love is having my receipts sent to my e-mail. That way I always have them.
