Unreliability of Tim Horton's on campus

I'm really annoyed today (Sunday, March 9) that Tim Horton's in the SLC is closed. Yes, it snowed yesterday. But today the university is open and I expect that Tim Horton's will fulfill the promise that has made by posting its hours. Somtimes it is closed without warning, such as today.

Posting a "Sorry for the inconvenience" note on their locked door is just unacceptable. They should have to follow some regulation that makes them inform the campus community prior to any unexpected closure.
