Two times now I have had customers want me to mow for them but someone else is mowing the lawn. The first one is a building lot that the new (yet to be built) home owner has to keep mowed till the house is started. I mowed it once, then every time I went by someone else had mowed it. I let the owner know what was going on, but they can't find out who is mowing it. The homes on each side are still being built so its not them. The second one is a person with their house here for sale, they live in a different state. I went to mow for the second time and someone had mowed it a day or two ago. I just sent him an E-Mail to let him know what was up and see if he still wanted me to try to mow. Any of you guys have this happen?
