Religiously Affiliated Businesses

This truck was found in Valparaiso, Indiana on May 26, 2007 outside of the Northside Tap (a bar). I think it's such an interesting phenomenon that businesses like this drywall and painting company visibly ally themselves with a religious motif. Perhaps this a technique that snags them a loyal clientele, however, it could also alienate perspective customers. Generally, I don't believe that it matters to consumers if their handyman is religious or not.
