Nope.
Just goodwill. It's happened to me and I've heard along with read of it happening with others.
My example is having to take my iMac 27" into a Genius appointment as the screen flickered.
Although the employee helping me couldn't replicate the issue he was able to run a diagnostic and see it had happened.
He suggested a replacement even though I was well past any warranty (no Apple care) instead of a fix. When he returned from the back of the store he brought me an upgrade model as they were out of the one I brought in.
He stood next to a manager who signed off on this exchange.
Now, more specific to the OP's thread, when I purchased my iMac I honestly, and as it turned out, incorrectly thought it came with a Magic mouse along with a wireless tracking pad. Turns out it is one or the other.
Without missing a beat the salesman offered me both without me asking.
I rarely have issues with Apple products but when I do I have been greeted with kindness and true assistance and, as the example above demonstrates along with the example the OP stated, sometimes the service is over and beyond what is expected.
