Stuck an estimate on a door a couple weeks ago. Lady calls a couple days ago. we play phone tag for a couple more days. Finally she leaves me a message to go ahead and do it. I pull up. Grass at 6-9 inches. Some weeds over a foot tall. I knock on the door. No answer. I call. No answer. Small yard. Original quote was for 25. I called left message that we were there and that it was going to cost more for the mow. Wait a few more minutes. No call. Go ahead and mow. Have to mow it twice to get it looking nice. We finish and move on to the next job. Customer calls back and says the yard looks great and how much did she owe me. I tell her 45. She says she will put it in the mail box. I pull back up to the house to get it and along with the check i get a letter saying not to mow it again. I should have charged her 55+.
