Today I had to go to a long time customer's house. As usual I show up to do one task and she has a "Honey-do" list waiting for me. I have a few customers like this.
I was called to fix some shower tile that fell off (which I did fix) but she was telling me how her water bill was through the roof. She had hired a professional plumber to fix the leaks but instead of fixing them he just fixed at them using old used parts. When she called him to come back and fix it right he conveniently didn't have the time.
So I went throughout the house fixing all the leaks that he was paid to fix and didn't. This is how I get repeat business. I go above and beyond what is expected whenever possible.
She had an appointment that she had to get to so I told her that I'll just sit in my truck until she gets back. Looking in my side mirror I saw a little visitor who came to keep an eye on me.
