We generally run on a staff of 10 or less, and we all work really hard. All employees here are treated like family...we DO also think of our customers as family, but that does mean if you are "tormenting" one of our "little brothers or sisters", we'll "ground" you. And if you're *really* naughty, you might get a policy named after you. So just be nice, ok? You be nice to us, and we'll do our best for you! That's a promise.
