"The Whittler"...very funny, I think I've met him. His cousin is called "the Chiseler" and they honed their technique together!
Seriously, here is another The Molalla Bid Game. I call it this as it is named after a town far on the outskirts of the metropolis. Its in the hinterlands. People don't often have a whole lot of money there, but they have big acreages. Customer calls you up to give a complete itemized quote on all of the trees on her 5 acre estate, detailing the priorities of things to be done and when. You diligently prepare it, knowing there is some uncertainty as to the outcome but convinced that duty requires you to complete your free estimate to the customer. You never hear from them again or, if you do, they mention that they don't have the money or will just do it themselves (the husband is an old logger). This is when a free quote becomes a give away tree evaluation/informal plant disease assessment/ tree inventory.
