The way I see it, you've got two realms here: The chain stores that go by mediocre but usually enforced guidelines set by a large corporate office, OR a free-for-all world where where some small pet stores take excellent care of their animals... but most others screw up horribly. I'm not sure what's worse.
Wouldn't it be nice if more people cared more than two cents worth about herps? Then maybe we wouldn't have this problem.
