Actually, that is an *excellent* analogy.
It was a manufacturing defect - the item inside was not the colour that was labelled on the outside (brand new item, not used incidentally).
I did not make the product and I was not with the product for 24 hours a day, 365 days a year.
I was reasonably sure that the product inside was what was labelled on the outside, because that is what I'd seen with my own eyes.
I asked the person who had packaged the item, they told me that if they had packaged it, it was definetely the correct colour.
However, an accident/mixup happened to the product at some point in its lifespan that I was not aware of.
Sort of just like your road...
You're the one quoting the colour issue from another newsgroup and don't even appear to have comprehended it was a manufacturing defect and not a mistake on my part, despite my clearly saying "it was a manufacturing defect". It was also "item", not "items".
So who's not paying attention ? :)
Anyway chap, chill a bit. I did say previously that you were probably right. All I was trying to do is point out that things happen that you do not know about.
