My favorite LFS in town doesn't require a sample to purchase fish, but they do require one for returning fish, regardless of what else was purchased at the time.
They also have signs posted explaining that fish do not "grow to the tank size", and all of their labels are accurate, containing both common and scientific names, and true adult sizes. They are also very knowledgeable, with specific experts in saltwater, cichlids, freshwater, and plants, that handle sales/questions in those corresponding areas of the shop. They won't refuse a sale to a customer, but they do everything they can to inform their customers prior to purchase.
Personally, I would rather see things the way you describe Jason, but like you mentioned, the business wouldn't last long. This LFS is realistically about as good as it gets when it comes to the balance between business & ethics when it comes to aquatic life.
If anyone lives in the Eugene/Springfield area of Oregon, the place is called Aqua Serene. If you haven't been there, it's worth checking out!
...ok, gonna stop incidentally bumping this ancient thread now...
But I was still getting sooo aggravated with the OP refusing to listen to anyone! Why would they have even asked for help??!?
