Buddy of mine's brother worked the past 2 summers with one of the big times said he needs a few extra dollars because he's wanting to buy his girlfriend an engagement ring. I said well do you know how to sharpen blades, do oil changes, etc.? He said of course I do that was our responsibility with (the other company). So boom he's hired for that purpose while I go out and cut my few clients lawns for that day. Get back and he's all dejected looking and I said "what's the matter with you?" and he said "man, I think I screwed up your pushmower" I said "WHAT DO YOU MEAN?" he said "I was took the blade off the mower to sharpen it and after I put the blade back on I (here's the good part) turn the mower right side up and then all this oil comes pouring out." Needless to say I was a tad pis$ed. No more, I don't care how good a friend he is, I'm still new to this business and I can't afford someone screwing up my equipment. Anybody else ever had anything even remotely similar to this happen before?
