We once had a brick and mortar antique shop. Sometimes I was forced to "man" it. It was pretty clear that there were visitors with a wide range of motivations. Some really just wanted to interact with people and so it didn't matter what was there to read, they were going to ask anyway. There were also a lot of people who were playing a game and they won if they haggled down to "their price". I don't know how many times people refused to believe something was my best offer or got offended when the negotiation went: $5 (price tag). $3.00 (offer), $4.00 (counter offer), $3.50 (counter), $4.00 (firm), No Thanks (accompanied with some sense annoyance). And while we may not all have the same definition of "stupid" I think we can agree that, however it is defined, "You can't fix Stupid."
