If it is before 11:00AM you better have a breakfast option, the same goes for lunch from 11:30-12:30.
But what it certainly does not entail is having to rely on only yourself to produce a well maintained meeting. If you are part of a team of co-workers they should be there helping set up and definitely helping clean up and take down.
Also? Do not ever think of just leaving any space a mess for the janitor to clean up. I don't care if you are Bill Gates or Barack Obama...okay, they probably hire people for that....but it is still rude as can be.
But mainly I shouldn't have to ask you three times to get up from your cubicle to come help me clean up a pigsty that resulted from a two hour morning meeting.
The end.
