Opening up a wound and rubbing salt in it what happened Cintas?

When talking about Cintas you cannot forget Unifirst they are in the same industry and are so fiercely competitive you will often see their buildings a couple miles apart and in the city you can see both Cintas and Unifirst trucks going business to business dropping off clothes and supplies. Just one big question what happened here??? Did Unifirst discover a magic detergent? Are they using Clorox products? Arm and Hammer?
