Is this serpentine belt too bad to worry about?

Hi,

In mid-Ferbruary 2008, I had a serpentine belt replaced as well as a
tensioner at a local auto repair shop here in Cleveland, Ohio. I have
a 1998 Dodge Caravan SE, 3.3. Two weeks later, the belt loosened, but
didn't fall completely off. I was lucky enough to be able to carefully
drive my Caravan back to the shop. They fixed it for free. I assume
they didn't put it on right the first time, maybe not enough tension
on it.

I just had the hood open yesterday to do my weekly maintenance, such
as checking the fluids, etc., and I seen the belt as it is in the
picture linked above. Must be one bad spot that aligned itself up just
right this time that I can see it. Is this worth a trip back to the
shop, or is it not bad enough to worry about? Looks pretty impressive
to me, and I can even see what looks like a slight crease across the
belt.

I have a hunch they put the same belt back on that just came loose,
that got damaged when it was coming loose.

Thanks.
