I posted this in April last year:
"At an event a few weeks ago I'm flicking thru a very well known record dealer's box, while chatting to him and another DJ/mate of mine. In the background a record came on which all 3 of us turned and listened to and made favourable comments, not being quite sure what the record was. The dealer then remembered who it was and it's title, ....and by amazing coincidence I had just found it in his sales box, so I pulled it and said, "great, I'll have this".....at which the dealer took it from me and said "sorry i'm keeping it". I thought he was joking, so did my mate, but no, he was serious. "
It was a 30 quidder (!) and turned out to be not too hard to find a few weeks later. I've spent 1000's pounds with this dealer over the years, and for the sake of 30 quid he's lost me as a customer who would probably spend 1,000's in the future.
