I have never played the firefighter career yet so I decided to take my Sim to the fire station just to see what it looked like. Well, no one was there so she spent part of a day and all night there. She ate, painted, used the inventing bench, showered, slept, etc. and no one cared. Is that the way it always works? I had a Sim with nothing running all over town to shower, eat free, etc. and here the fire station had it all. I expected firemen to come in any minute and kick her out but it never happened. So now I wonder if you could basically live at the fire station.
