Don't touch the touch screen!

Point of Sale terminal, The Home Depot, Cambie Street, Vancouver

The whole point of a touch screen is that you can touch it. But here is a poor implementation of the technology.

Who is to blame? The screen manufacturer, or The Home Depot for not testing the equipment thoroughly? I'd say both, but The Home Depot must bear the larger portion of the blame.

Before anything is rolled out to the retail stores it should be thoroughly tested, and a touch screen that actually works by touch would seem to be a pretty basic requirement.

Of course there may be another issue. Perhaps the screen is only meant to be used with the pen, in which case the term "touch screen" is confusingly inappropriate.
