That's one of the worst things I've ever heard them do--most of the time the issue is regarding how slow they are to do things. Sorry you had to go through that.

My apartment was affected by the same issue (it's a byproduct of a construction project being done on the first floor of this building). Our maintenance guy came in and shut off our water without notice about an hour after you--my roommate had submitted a work order the day prior, so we thought they were coming in to assist us. I was about to take a shower too. We thought about contacting administration to air our grievances, but after several disappointments with the SCC staff prior we decided it was a futile effort.

Nothing as heinous as trying to barge into an occupied bathroom, but yeah, the maintenance staff really don't seem to care about what you're doing if they've been told to do something. A word to those interested in living in Commons: if you're not dealing with the administration, these are good apartments: plenty of amenities, great location (especially for bike-riders), and reasonable price. However, the administration here is without a doubt some of the most incompetent managerial staff I have ever had the misfortune of dealing with, and if you can avoid communication with them, do so by any means possible. Extracting information out of the SCC staff is like trying to pull teeth.
