.......... bad ideas are at times creative !(a big hole for the big cat & a
small one for a small cat !! - when Archemedies can do this whynot we !)
.......... the terms actor and system are conceptual and relative........
they can be often interchanged also. But,...... every actor has to finally
translate his logical thinking into some form of action through a system or
user interface. An actor may ask a "Manager to buy soap" or attend the "Soap
Opera" (some silly action !)- but how does he indicate his decision ! ... I
have already given the example of Super ordinate & sub-ordinate systems! in
my earlier response !
Hope I have undersood your Question & this helps !

Hey,
No, that is a bad idea. It certainly doesn't reflect what would happen in
real life.
Such a system might achieve what you want by, for example, adding an item to
the 'manager's purchase request list'. In this case, you should have a use
case that reflects this - 'add item to purchase request list'. You might
also have a use case with the manager as an actor that is something like
'read purchase request list'.
In a general sense an actor instigates a use case.
