Depending on where your character is working, your GM decides what the appropriate modifier for working conditions is. You're free to argue if you think the location isn't as bad as the GM says it is, though. Just try not to get too aggressive and start a fight or anything. Like "Your apartment living room is Terrible, -4." "It's not that bad; my character just moved in, there's no mess and lots of room." "Well, alright... It's still not great, but maybe just Poor is fine. Building a drone on a coffee table is far from ideal."
