Okay I have an account that i have been mowing for 2 years now and last year this guy was a great customer. This season he is always complaining about my price being raised $5... All he does is complain, no more compliments. The problem is that he has 2 young kids and they leave toys all over the yard. I mow their lawn on the same day every week and stuff is all over the lawn EVERY time. (toys, chairs, baseball bats, balls and a trampoline). I have told him many times that he knows what day i am coming so keep the lawn semi-clean. He hasn't done anything and I have said something to him 3 times. What do i do now?
