Last fall I aerated a lawn from one of my ads I was running. They liked the service and wanted me to start a full service in the spring( mow fert&squirt, etc.) Now the problem. I charge if they don't pick up after their dog. The customer doesn't have a dog, but the neighbor does and it likes to crap in their yard. The customer says that they will pick up before I come. What do you do when the yard is not picked up from the dog. The yard is very well maintained but the customer is getting older and would like to go out fishing more than yard work. I am sure he does not want to stir up problems with the neighbor about the dog. It has been going on for years from what he said.
