My first job doing someones lawn and it ended bad because of a dimwitted customer. I get a call from a guy that has a lawn which dosen't look too good and asks if I can do a job repairing it for him. I say sure, no problem, done this a million times. So I go over there, bring my equipment and his wife is there to show me the lawn and what they want it to look like, showing some magazine pictures of what looks like an almost golf course green. I take a few 'before pics', before work commences. I read somewhere its good to start by trimming the grass as short as possible and then aerating it so that the grass will grow back stronger and to fertilize and after-sow a few seeds here and there to get it just right. So I tell her my plan and what needs to be done and she accepts and goes back inside. I start by the above procedure and after that, get underway by aerating the lawn. Then a few 'after pics' to document the progress. But now, get this, just about 5 mins after I'm done aerating, the guy comes home, parks his car and quickly calls his wife and approaches me, asking what the hell I've done here! I tell him to chill, that I've already explained to his wife how to get a good golf course grass gowing and the procedure involved. He has the nerve to tell me that its all wrong, that I didn't use an aerator but a cultivator and that I've completely ruined and chunked his lawn to bits. I tell him that if hes so clever he could do this himself, instead of hiring a professional and reassure him that is it what needs to be done, that the grass will grow back stronger and it'll be flatter than before. His wife was just standing there with gaping jaw and red as a turnip, as if she forgot to take her medication or something. So much for telling him that we've talked this through before work commenced and taking my side of the matter. After a few moments of silence and I can clearly see their anger, I decide to further reassure them that this is the best thing to do as it also kills many of the harmful bugs in the lawn, like the ghastly earthworms that do no good whatsoever. At this, his wife flings out a stream of insults and I get angry too and tell the husband to keep her on a leash if he can't control his animal. He gets all menacy and I decide the best thing to do is quickly pack my things and just take off, WITHOUT payment! I think the problem is they're having maritial problems and they needed to vent it out on me. Have any of you also encountered some non-paying jobs because of stupid customers that can't tell the difference between lawn and concrete? Attached are pics of before, during and after the aeration.
