saying, but in business you need to complete the task that you have started, and i believe you must always give more than you promise. in other words, you should have at least brushed the dog's front teeth and given him a chew bone to get rid of the bad breath. this way, not only did you complete the tasks you charged for, but you put in a value added item – the tooth brushing without having to be told to do it. this is how you impress a customer and keep them coming back for more – you give more of yourself than they expect and are paying for.
