You need a personalized approach if there is an issue raised by customers in relation to how they are served by the workers in a retail or in wholesale department. This may happen if the time is not managed well by the workers. They might work so slow or keep on talking while working forgetting about the constraint of time and the annoying feeling of the customers that like to blow in anger. The owner needs to personalize to seriously achieve any extra efficiency work in the day and to answer the claim of the customers of the workers' performances. If the owner is watching the workers. They will work fast and focus only on their work. There are abusive workers who are relaxing when the business owner is not around. What can you say peps?
