1B8 is Lisa QQ's office.
Although from time to time when she is taking some time off she rents the room out to others.There seem to be other doors on this floor with no signs on them, and they are used by a rotating cohort of operators operating irregularly. With these kind of folks, when I meet them and like them, I get their mobile telephone number as they will regularly work out of different rooms in the building.
Keep on mongering
