Honestly, the position I prefer to be in. It confirms you know their taste.
NOW, you want a truly disturbing version of this? Try getting it right, only its the more expensive one, so she refuses to buy it or let you pay the difference, or even buy it for her! … and with the way these sales and store-stock rotation work, its often not so easy as coming back next month, next week … even the same day, to get it for whatever-next-holiday-that-probably-falls-too-late-in-the-season-anyway. Sneak a picture of the tag? Congratulations, its somehow out-of-stock or never sold on-line, nor in nearby stores.
People that are convinced they are going to be the next sales/shopping/couponing deity are the WORST to want good things for. Short route to fadish or gimped products that do not work as well as advertized, or in the case of things like Black Friday televisions, what you would otherwise get them if they would only let you when there’s time to be certain.
Before you read too much into that last sentence, the minimum age of a TV or monitor in my house is ten years old, and the average close to 15. As a former professional PC, TV, Printer and Appliance repair man, that’s one bite from this I managed to avoid while still letting it give me nightmares.
