i have been doing this for quite some time. I mow around retail parking lots and have mowed around in behind, beside, in front of thousands of cars. I'm sure many of you have seen how people back in a lot clear up to the curb with their back wheels and as close as possible. In 16 years I have had 4 complaints of grass on cars. Normally the grass would be off before they leave the lot. I always offer money for a car wash 10.00 mainly just to get the people moving and so they don't complain to the stores. I have had one taker. The other 3 just want to be in charge and complain even after offering a car wash (cash money). Today I had a man complain because my worker got and I counted them 3 slivers of grass on his truck. 1/4 inch long. My guy was trimming in the area when he pulled up 1 inch from the curb.The guy came out looking for a argument. He looked all over the truck seen the 3 slivers and just went kind of crazy. After saying we are sorry, offering a car wash several times and him not taking, I had the money in my hand offering it to him. I finally just walked off while he continued to complain. We are always very careful and often won't trim until the area is clear and then go back. This is often impossible to do. OK how would you all handle this situation ? You can be serious or funny as he**. I just need some feed back. Thanks !!
