How do you deal with a bad custome that is also your boss at work?

My husbands boss bought a lawnmower from him and asked him to fix a trimmer. My husband has a hobby of fixing up things like lawnmowers and he sells the used lawnmowers that he fixes up-not for really any profit at all. And they do run very good even years later.





My husband told him that he could try to fix the trimmer and did have a lawnmower-a very nice one. Well a few days after selling it his boss called and told him to pick up the lawnmower and fix it again because it was not running right. He did and it worked good-then the next day his boss told him that he didn%26#039;t want it anymore and to give him the money back from it. My husband did, but was a little mad about it. Now his boss is doing the same thing with the trimmer. His boss told him him that he would bring it into work tomarrow so he could fix it-for no extra money. He does not want to deal with this again! But does not know how to tell him he will not fix this again. How would you handle a person like this? Thanks

You could %26quot;recommend%26quot; someone else to do further fix jobs.
