Are they marked and well-lit? Maybe a buzzer in the seat cushion? Can't assume everybody knows where not to sit. Just funnin' ya. I would be "irritated."There are like 5 people in the building and we have hotel cubicles set up for people that don't have a desk to set up to work. So naturally someone (I have no clue who) comes in and sits in the cube right next to me (not a hotel cubicle) and proceeds to talk on the phone the entire time
