About a month ago we picked up this account that a large company was doing. The homeowner said they were in there and out in five minutes and he wasn't satisfied. So anyways, the guy asked us to bag, and cut part of his yard a different height. So after the second week this guy is praising our work and was very happy. Then comes the fourth week. He was complaining that we cut his lawn shorter this time and caused his lawn to brown out. First off we have our mowers set and never change them, one shorter and two higher. Secondly, the logical reason why it browned out is that it hasnt rained in nearly two weeks and its been 100 degrees for the past week. So were considering dropping him if he continues to be a pain. What should we do, i dont know if hes worht our time.
