A digital signal will NEVER look like that. And HDTV is broadcast in
digital form. If they are getting that kind of thing with HD content,
then they are doing something abnormal with it, such as converting it
to an analog form from a single tuner and distributing it that way over
all the sets.
If they were taking OTA digital programming, and distributing it in the
RF form it comes over the air, but over the coax instead, it will either
work fine, or just die (maybe a few blocks of the image will fail). But
it will not look fuzzy, or snowy, or noisy, or have herringbones (unless
the set itself is defective).
My ham radio HT transmitting 5 watts of 144 MHz right next a TV does
tend to mess up most of them. I could expect that to happen to an HD
set as well. I doubt that is BB's issue. More likely it is a dumb
setup.
OTA broadcasts are still not all HD, so they are unlikely to depend on
that. But you should insist on watching local OTA broadcasts you know
to be in HD, using the set's built-in tuner (not some baseband setup
the store has) and see what you get.

It could be out of adjustment, or just cheap optics.

Amazingly, lots of people are buying despite the crappy job done by the
stores.

As for the manager of the store. Tell them the signal you are watching
_may_ be originally an HD signal, but it is _obviously_ not being sent
to the set in digital form. Suggest to him that he correct that problem.
Suggest to him that he will sell more sets, and move more inventory, if
the sets look better than crap. Tell him you'll put off your purchase
for another week and come back and if the problem is not fixed, you will
be buying at another store.
But you may not even be seeing HD content.
