Twice this has happened with the same customer. She calls the day before mow day to tell me it doesn't need it. Then she'll cut it herself before the next week but she will not trim or do the pool area. Then she calls and wonders why I charge the bi-weekly rate when she "cut the lawn to make it easier for me". I assume she is just trying to save money, or she enjoys pushing the mower around every once in a while. I don't know. I think its time to charge $5 for phone support or something.
