Normally, when a customer says that, they are just being cheap. And when a biweekly customer says that, they are one step from being canceled. Last week, I had a biweekly customer say that and so I skipped them. I mowed the lawn across the street a couple of days ago and glanced over expecting to see an overgrown mess that I would be expected to clean up but she was right, there was no growth. In fact, her lawn wasn't even green. I mentioned that to my wife this evening and she told me that when the customer called, she had said that her grandson had sprayed weed killer on the lawn and that was why it wasn't growing. I suspect he used Round-up. It did, however, kill all of the weeds.
