One of my clients, a senior widow, calls me the day before her scheduled cut week before last, and tells me that her lawn did not require cutting that week. (she has done this a few times over the summer when it wasn't growing quite as fast) Anyways, I'm thinking, all the other lawns have been growing like crazy and hers was very long the week before when I cut, so how is it that hers has not grown? Also it was just fertilized a few weeks prior. I had to pass her house anyways, so I stopped in to look and sure enough, it was 6" to 7" long. When I talked to her, she seemed upset that I came by to look but still insisted that it did NOT need cutting. I get the feeling she must think that since I just cut grass for a living, that I must be stupid. So I told her that I probably won't be back next week either as it needs it THIS week. I was going to drop her. She has been a pain in other things as well. Well I got to thinking that I want to show her just how badly that it should have been cut the week before so I called the next week and asked her if it needed cutting now. She replies "Yes it needs it now. But only if you are going to charge me for just one cut". (That was the perfect question) I says "Sure, I'm only going to cut it once". I NEVER leave clippings showing on the lawns. Double cut or even bag if I have to (for customers that don't cancel cuts) But on this cut, my mower was having trouble going through at normal speed. Had to slow right down. Even then it was leaving some uncut strips. The grass was 8" to 9" long, thick & wet. Still, it took about the normal time. What a friggin mess. Looked like a hay field or worse. She left my payment in the back porch like usual, so I scooped that and left. (and I probably won't be back) I don't like to leave lawns like that but I needed to prove a point. Sorry for the long post. What would you guys have done?
