well, it's the same people after all.....I often wonder the same thing
I was asked by a department in my office to spec out laptops for them. THey had an idea of what they wanted and told me. After a couple days I came back with the laptops I recommended and also told them the one they were looking at is nothing but trouble as well as telling them "Do Not Order It"........ they order the one I expressly told them not to order...several of them actually
Now I get to tell them, every single time they bring one to me to fix..... I told you so.....
Happens in the real world too
