I've had this customer since the beginning of last year. They are a senior couple with medical conditions that keep them housebound. They were very pleased with what I did for them last year and she even said that "I was a gardener after her own heart". Well, this year they always seem to have some attitude with me. When I would go to their door with some advice about fertilizing, watering, etc or their monthly invoice, they would only say a few words and practically close the door in my face. Four weeks ago, they called and said the lawn wasn't growing (we have been having a drought) and didn't need cutting. They have inground irrigation and obviously have been watering some. Since I also cut next door, I checked the lawn and it could have used a clean up but I let it go. The next week again they call and say don't cut yet. Again I check and the grass is about 5 - 6" lg, but I let it go. The third week they don't call, so I cut it. It was so long that I had to cut it 2 times and 3 times in some places. I only charge $25 per cut (seniors discount and 10 cuts on this street in a seniors village), but because it took twice as long to cut, I charged them $35, but not double. I explained in detail to her why the extra cost. WOW, a whole $35 from them for the entire month. She was not very pleased but did pay it. The next day she calls and says that they "No longer require my services, that they have hired someone else to cut". When I asked why, she said they didn't like my attitude???????? No, I don't have contracts, but am seriously considering it for next season. So many of these seniors must think that lawn cutters are only doing this for beer money.
