The picture that shows a bearded dragon and a uro in the same unlit, unheated cage with what looks like a large afrock crammed into a bare tank above is all I needed to see. Wherever those pictures are from.... they're not acceptable on any level regardless of who took them, who posted them, or for what reasons... in the photos DNJ posted as proof that they are OK, I see many snakes in caging with no real hides or places to tuck themselves away for a sense of security and privacy. A paper towel lining the bottom of an exo terra breeder box and nothing more is not an acceptable habitat for a snake, especially a BCI when it's out in the open and people are constantly walking by. It's stressful to the snakes, if nothing else. If you've got them tucked into a dark, properly heated rack that is one thing... but that's not the case there. I don't really think I even need to say anything about the small monitor as it would be beating a dead horse. I don't see what the OP (disgruntled customer syndrome is the worst) was describing, but I still don't see a whole lot of good.
The problem with having animals in bare cages with no hides, furnishings, or lighting and mixing species together is that YOU as a business establishment... an entity that people trust to be knowledgeable about these animals are sending the message to the general public that these kinds of cage setups are acceptable. How can you tell your customers a bearded dragon needs a hot basking area, UVB lighting, food ever day, water, etc, when none of those things are being provided on the store front? The answer is you can't. Because your customer is going to look at you like you are a hypocrite.
