I am not a Gen-Y-er (though being born in 1979, I’m not technically a GenX-er either), but I’m not sure what value is brought by expecting talented people (they are talented, that’s why they got hired, right) to immediately suffer through menial tasks that do not allow them any responsibility, encourage them to contribute, or include them as part of the team. What kind of lesson does that teach? It seems like needless discouragement to me.
I would say that if you have a Gen-Y-er on your team, a better strategy would be to include them in meetings, allow them to offer suggestions (even if you may think they’re dumb questions, it is your job to help them refine their thinking to come to a more workable idea), and generally value their contribution. If you meet all these needs, then you create an atmosphere where they want to get you coffee to show appreciation, rather than it being a chore to be resented.
Also, do this with everyone.
