Following a phone call from a charity shop (No not Oxfam) about a book, a woman arrived at the shop with the "ancient volume" for me to value on their behalf. Of course this was a completely dead 1960's piece of worthless tat, but never mind.
Having told her this (Very gently) I was about to return to my work when she commented that she had another 3 crates of books in her car outside for me to look at.
Although I nearly began my "Charity shops are bankrupting me" rant, I thought I would just be nice, and look at them for her. So i went out, and rummaged through the boxes, and gave her a few suggested prices for the better books, and suggested that she give the rest to a charity shop she didn't like.
Although it is tempting to leave this as a tale of the presumption and cheek of the charity sector, sadly due to my policy of truth and honesty I can't.
She produced a box of chocolates and big thanks for my time. I felt most touched, and only afterwards wondered who would have eaten the chocolates if I hadn't agreed to go out and value the crates of books.
But please local charities - don't take this as a suggestion that you all come along with you books for me to value. With 22 charity shops in the town centre, I wouldn't have time to do anything else.
