I was doing some mulch work at this one house and I backed my truck and trailer into their driveway so I could unload the mulch and all and then the guy comes out and hes like I need you to move so I can get out meanwhile their car is on the other side of the driveway and he could have moved it himself, and I asked him to and hes like you have to move so I moved the truck but b/c i had taken some of the mulch off the back of the trailer that pushed the front of the trailer down b/c there was less weight behind the tires and when i pulled out it left this mark in his driveway cuz part of the trailer hit it left like a 2 inch by 4 inch by .25" mark. I told his wife and shes like oh don't worry about it so i didn't. I even offered to fix it for them for free, and shes like no don't worry about it so i didn't and i just got the check today for the job and they subtracted about $78 for the "driveway repair". I had done work earlier this year, a $450 mulch and edging job in the back of the house. They told me to just do the front and then let them know what they owed me. For mulch install I figured $300 and then I added only $15 for edging when It should have been at least 30 b/c i felt bad for the driveway. So the bill was for $315 and they sent a check for $237. I think $78 to fix that mark in the driveway is just not right. What would you guys do?
