Male Customer: Can you show me where the calci sand is?
Me, a girl: Sure! But first can I ask what you’re going to keep on it?
Customer: a bearded dragon.
Me: Alright, unfortunately calci sand, and other loose substrates, have a history of causing impaction in reptiles.
Customer: ?? What’s that???
Me: You know how when sand gets wet it clumps together? Imagine that happening inside your babies tummy! Then he can’t pass anything, and there’s a high risk of them dying. How about I show you some other substrate options?
Customer: No, that’s wrong. The guy at the other petstore said calci sand was the best!
Me: … uh he might have been confused. I have a few reptiles at home and have done lots of research on this. I can recommend you to some forums, if you would like?
Customer: No! The man at the other store said this was a good option, and I trust him!
