Would'nt the fact that the doors are opened/closed all day equalize pressures?...maybe they leave some exhaust fans on over night. I'll ask the mngr....
Think about how the doors are. Does the exterior door go directly into the store or into an entry way and then another door into the store.
When you open the door to the store did you feel air rushing onto your face or being sucked in? If air is being pushed out the open door then the building has a positive pressure. This is what you want.
