Ok so I got this idea... I was supposed to go mow it again today. So far, ALL of the work for the season is on that one bill I sent him. I will show up and hand deliver the revised bill with the cleanup fee and minus the $5.50, and get a check written on the spot for that. Then once I have check in hand I will hand him a cancellation letter and get outta there... while walking back to the truck he will think I'm going to get my equipment off and start mowing, but he'll start reading the letter and about the time i'm getting in my truck and taking off, the letter will sink in and realization will come to effect... hahahaha.. I love it! Will post back tonight and let you all know how it goes.
