i have this group of homes. 5 in a row. from mid october to the end of november it is a living hell. oak trees, big ones, and lots of them. i try to get there twice a week , once for a quick 20 min blow on each property, then later in the week for a more thorough cleaning. well, i had a problem with one of the customers about 2 yrs ago, and we parted ways, on good terms, just parted ways. the nicest, sweetest guy i ever met. anyhow, the new lawnboy turned his place to crap. weeds, crabgrass, just garbage. he came to me in august and asked if i'd take him back. sure, no problem. i wrote up a contract. he said, "screw that contract, take it home with you. and here is payment in full for the rest of the year. " and i charge big bucks for this area, it's rough work. so, anyhow, when i go there mid week to do my quick blowing of the leaves, his property is already clean. hmmm, ok. when i go there on saturdays, he hears my blower down the street, and comes out and gets his, and cleans his property. by the time i get to him, it's almost done, and i only have 20 min of work there. this happens every week. yesterday i said, "ok, look, bill, are you trying to steal my job?" he says, "no, just want to help." i said, "well i'm not giving any refunds." he says, "i don't want any." this is very awkward to me. what would you do?
