I did a lawn right next to one of my regulars. The woman hadn't had the grass cut yet this year. She knew I was coming by to do my regular. When I got there I wasn't on the trimmer 2 minutes and she stopped me. I gave her a price that equaled out to almost $100hr and she jumped all over it. She is now a weekly customer right next door to my other.
I should have gotten pics. It was a lot taller then what the OP posted.
