I had a lady who I could never cut the grass short enough for her. Lower, lower, lower. I explained in Texas if you cut it that short its going to burn cause its so hot. Still didnt listen, so it burned. Still though, with burnt grass she wanted me to mow it lower. Dirt is flying up, taking off inches of top soil. People driving by can only see me from the waist up im cutting it so low, but I do it to humor her, chuckling the whole time I destroyed her yard. Then after Im all done, she looks at me with a straight face and says, "You know, I think it might be too short." I asked for payment and never mowed again, not as if there would be anything to mow for awhile.
