I have worked in cube farms for most of my career.
In addition to the above suggestions, please don't sit at your desk and call the name of someone in another cube "to see if they are at their desk".
I hate hearing people just randomly call out my name. Or having conversations between the cubicle on my left and the cubicle on my right...they sit at their desks and loudly converse to one another.
We have an in-house instant messaging system. Because we are spread out for multiple buildings, this is a handy way to contact someone for a quick yes/no question.
It is linked to our calendars and email. If someone wants to IM or email, when they look up a name there will be a dot next to it.
Green means available.
Yellow means there is something on the calendar and the person is unavailable.
Red means AFK for more than 10 minutes.
I really love that system!
About the food issues....please no FISH in the microwave. One of the guys in my cube farm brings in left overs (no problem) which often include fried or grilled fish.
Yesterday, I could smell it from within the stairwell which is separated from our cube farm by a fire door, hallway, and another fire door.
