Wrong. Please read the whole post. I basically said the manager may or may not have a clue on the iMac.
I DID read it but didn't find it relevant to answer. But, here's the answer for your sake.
Apple like other organisations do have 'assistant managers'. Furthermore, managers are not likely to be on vacation for a week at Cupertino. They're probably there for the one day or less for the meeting. More so, I can't see every single Apple store manager being invited to this meeting - theres probably a head of each continent i.e. Europe, Asia etc... who are most probably invited. Again, thats my own thoughts but I can't see every single store manager being invited from across the world. It is possible, but even then they have at least two managers and then the assistant managers.
