i show up yesterday to mow, and i see it was cut, real low, with a 21". i start my mower, and run over the lawn. she comes out, and says, "o, i didn't know if u were comming, so i cut it." i said, "ok, i still have to go thru the motions, afterall, you are paying for it. " she didn't like that. also, i am considering sending a letter saying that since she mowed it herself, and she mowed it way too low, and with an obvious dull blade, i will not be available to answer to any complaints about weeds or turf quality. i treat this first year "troubled" property also, and i cut at heights of 3+ inches, and use sharp blades. ever have anything like this happen?
