I share an office with another person, and everyone walks through my office to get to a general file storage area. People say "Hi." as they walk through and I say "Hi." back. They respect me when I am busy on my computer and won't start a conversation with me but will stay to talk to me if I initiate the conversation.
The strangest thing about this room was the smell of marijuana in the summer. I work in a law enforcement crime lab and my office was next to the marijuana vault which was not ventilated very well. When the outside temperature would go over 85F, the smell started and would get overwhelming as the temperature increased. Once they figured out the ventilation fans were turned off and turned them back on, the smell was less. For 4 years, I lived with the smell. People would walk in and go "Eww. It stinks." and I would say "What smell?" as I would get used to it. Finally they renovated the storage area and moved the vault away from the offices.
The other issue with the room is the air/heat. The supply for the ac/heat goes done the hallway, and the duct to my room branches off and makes a U-turn to return to my office. The thermostat is in a room about 25 feet from me, so if the staff in that room get too cold/hot, they adjust the temperature for themselves and I get hot or cold. My office goes from 84 in the summer to 70 in the winter and it is always stuffy. They can't fix it and office space is at a premium, so I can't move anywhere else.
I would prefer an office to myself without traffic and a thermostat I can control.
