Friendly voice from a neighbouring town (30 miles away) called.
"afternoon - I'd like you to come and value my books"
"Are they for sale"
"No, I'd just like to know their value"
"well we would have to charge you a fair bit of money to drive out and do that"
"Oh, don't you do it for free ? I'm not willing to pay anything for it. Won't you just come and tell me what they are worth?"
