I had a customer take me up on a quote made 3 years ago, last November. It was for £28, I revisited and reqoted her a revised price of £32. She accepted, and confessed that she thought I was too expensive, so she went with someone else who didn't bother starting the job, then another window cleaner who used to leave fAg buts in her garden and just stopped coming after 8 months and she was going to try another guy but found my quote slip tucked under the microwave. Lol
