Here's a recent one.
THis guy was looking at the saltwater section of my LFS. One of the employees asked him what he was looking for. The customer says, "I want a clownfish for my current tank". THe employee asks him what he already has in there. The customer says, " a school of 12 neon tetras". The employee looks really confused now. "Uh, tetras are freshwater....." Ignorant customer says, "Oh, what's the difference?" I don't know what happened after that, I walked away.
