I just bought lunch at Quizno's. On top of a cabinet, between the cash register and the fountaion drink machine, in essentially the most prominent place in the establishment is this little framed 3" square metal plaque. It's like a little boiler plate off a machine  the lettering is stamped into the metal.
This is what is on the plaque:
I have no idea what the purpose of this little plaque is. Takers?

Perhaps the display is not a functional component at all. Perhaps it is aesthetic.
It would appear to be a magic square... Indeed, Googling "magic square 33" turns it up many times:

This looks to be what I heard to be called a Magic Square. It is a unique square matrix where the sum of any row, column, and diagonal will equal some constant. From what I know, this is the only requirement of the Magic Square however I have only seen ones where the constant that each row, column, and diagonal sum equals is
Matrix Constant= n(n^2+1)/2. where n is the dimension of the square matrix (also I think a 2x2 doesn't exist, but 1,3,4,5,...etc does). Since this matrix satisfies the rule of Magic Squares. Then the question I would be curious to ask is what is the significance of this matrix being at Quizno's?

1] It is a proud display of some manager's child's abilities at either math or machine shop or both. 2] Some manager is a math buff and is just waiting for someone to ask what that plaque is for...

3] (The winner): It was a gift, as a good luck charm. The manager had no idea of the significance of the numbers until I pointed it out.

1] some other manager's child's with the abilities at either math or machine shop or both. 2] Some other manager that is a math buff ?

I gathered pretty quickly that there was no math appreciation in the giver here, simply some superstition around magic squares.
