In the Refrigerator?

I went to get my lunch from the refrigerator today. By the time, I get there it's usually pretty empty as I don't eat lunch until 1 / 1:30 if I can help it.
There sitting in the middle of the top shelf was a "Maple Brown Sugar" granola bar.
Why would you refrigerate a granola bar?
Is granola better cold?
Have I been f*-ing it up all these years eating it at room temperature?
It just doesn't seem like the kind of food that would benefit from being cold.

Don't be offended if you love cold granola.
To each their own.
Just explain it to me. The why part, I get the what and the how.
