Another reason to hate Mondays

The three of us go to Canziani's (right downstairs) a couple times a day, on most days. We've dialled in our orders: Baby Girl has a cup of schiuma, the milk foam that is mixed into a cappucino. Susan has a cappucino, I have a double espresso lungo macchiato (with a little extra water and a dollop of schiuma).

But on Mondays, Canziani's is closed - buttoned up tight. There are other spots within a few blocks, but it's just not the same. How could it be?
