I'm probably in danger of over explaining the joke, but this actually does happen. The best part about this is people will actually contact support for online stores and just say that they found an item. No concern, no questions, just hi I found this. There are people that will do this every week, for years.
New customer service agents will go through the steps, how can I help you with it? Were you looking for a different item? Etc etc. And the conversation will go absolutely nowhere because no one knows why the hell people like this do these things and the customer will never provide any information. Eventually you give up and just say that's great! You can go ahead and buy it!
And the customer will say "ok thx" and disappear until next time. Most of the time these people never even place any orders.
