Not unethical.
In my business I run across things like this fairly often. (not cues but stuff in general) Things that are worth something to someone but the person who owns them isn't interested in trying to get top dollar or spending time getting multiple inputs. I recently had a customer that had ordered about 30k worth of furniture and when it arrived she didn't like the color and told the gardener to get rid of it. He didn't quite understand what "get rid of it" meant and asked her to clarify and she just said to take it to the dumps. So he kept it obviously. If the KCD buys a cue for $250 and sells it for $300 is this unethical? You can't look at the "profit" as the determining factor for it being unethical. It's all relative.AtLarge said:"Hypothetical" scenario.
A widow is disposing of some of her recently-deceased husband's possessions, including an old pool cue. The cue-ignorant widow is advised to contact Knowledgeable Cue Dealer (KCD) to discuss the cue. KCD goes to her house, inspects the cue, and asks her how much she wants for it. She says she doesn't know, it has just been lying around in the attic for most of the past 35 years, .............., how about $250? KCD pays her the money and leaves with the cue.
The next day, KCD calls one of his cue-collecting customers and sells the highly inlaid Balabushka cue for $25,000.
Was KCD unethical, just lucky, or something else?
