In this week's Business Scotland, the programme asks just how much can companies save on water bills through competition. Douglas Fraser talks to Mark Poles of Business Stream. Also on the programme the attraction of franchises, Douglas discusses the pros and cons of the business model with David Kaye from the law firm Harpers McLeod and hears from Pauline O'Neil from The Streat cafe in Glasgow city centre.
