You can tell how much a newsagent supplier trusts their products and services by how much they gossip about their competitors. Smart newsagents see this gossip for what it is. Unfortunately, some take gossip as true and find out later that they have been duped.
Professional gossipers are smart, they usually don’t gossip in writing. Their goal is to fan a fire of Chinese whispers.
Next time a supplier tells you something about a competitor, ask them why they think you should know this and ask them for proof. Who know, your challenge could stop their game playing and force them to focus on their products and services.
