So I rented an aerator yesterday to do my property along with my in-laws and a neighbors properties. Another neighbor of mine asked if he could split the cost of the machine with me and I told him yes. He told me that he was going to a family party and that he would be home later to use the machine. In the meantime I did the three properties plus picked up three others and made some extra scratch. Well, it started to get late and my neighbor was no where to been found so I started to clean the machine. As I was cleaning the machine he finally gets home and comes over to see what was going on. At this time I figured that we had approx 30 minutes of day light left. I told him that I was prepping the machine to return to the rental shop and at that time he went off his rocker. I told him that he was more than welcome to use it, but it would need to be spotless and topped off when he returned it to me so I dont get charged by the rental shop. This is the clincher, he stated that why should he have to clean the entire machine when I used it on six properties and that he was using it just on his. WTF? I told him to pound the pavement and rent his own machine. Now over a stupid aerator there is going to be bad blood between us? Just cant win these days .
