Well said. I am not a mow and blow person. I am asked to fix lawns that are not responding to the capabilities of an untrained person. When I call an electrician, builder, or even my diesel mechanic, the last thing I am doing is fighting with him about how to fix something. My only questions are along the lines of how much will it cost and how long will it take to fix it. If I knew more than they did, they would not be called in the first place. I respect someone's knowledge and experience more than to treat then like the uneducated hired help.
