Regularly scheduled maintenance

I had a pleasant surprise during lunch on Wednesday when someone came into the corridor, walked by the kitchen, then came back and asked if I lived in room 442.  He was here to replace the fire alarm.  I can only figure it was regularly scheduled maintenance, as I hadn't been aware of anything not working.  Kind of reassuring that the owners of Flogsta do some maintenance on a regular schedule rather than just waiting until the residents reported that the building was falling apart.
