I have a customer who is a very kind couple, but they are as annoying as hell. While I am mowing the lawn they keep stopping me. "Jeff, are you going to get that spot trimed in the back?" They say. Or something like that, and I am not even done!!! I have so much time wasted on that lawn at least an hour each time I mow it, and it is a tiny lawn! I am not getting paid enough to stop that much. How would you handle someone like??
