This is an appeal from a small claims matter in which Alfred Cannonier, doing business as Motor Trend ("Motor Trend") sued Austin Thomas ("Thomas"). Motor Trend alleged that Thomas owed it money for overhauling the transmission on Thomas' automobile. Following a bench trial, the Small Claims Division of the Superior Court awarded a judgment in favor of Motor Trend. Thomas appeals, pro se, asserting that the trial court erred by (1) prohibiting him from presenting all of his evidence; (2) prohibiting him from asserting a counterclaim for loss of business; and (3) concluding that he was liable for the entire invoice for automotive services
