Yesterday I am edging a customer who has 4 inches of turf overlaping the sidewalk. So I stick edge it then grab the string trimmer to cross cut, clean up and whip the clumps of grass that are extra close to the curb that the edger missed. A car honks and backs up, I look at my work and think to myself I'm sure this is the best this place has looked in years and I bet I have a new client here about to ask for an estimate. Nope, he backs up and is staring at me through a shattered passenger window. Now, I have to deal with either higher insurance permimums or a major auto bill. All because I wanted to use three pieces of equipment instead of two to save 4 minutes on an 1.25 hour job. From now on, all edging jobs, the string stays on the truck. I figure if I continue doing it the same way, next time it will be a person walking back to me clutching their face with blood pouring out. Lesson learned.
