Thrown Out of the Store

So sometimes I have a hard time keeping my mouth shut. I was at a local big chain pet store pickup up some supplies. Anyway as I stood in the retile section I was listening to an employee pushing coil UVB bulbs as okay for beardies as well as freeze dried food, and red light bulbs for night heat to a customer buying a new bearded dragon. I decided to interject myself into the conversation and in a polite way said to the person buying the dragon that everything they were told was incorrect. The store employee said I was incorrect. When I asked how many dragons they had cared for personally they walked away and I had a talk with the customer. The employee came back with a manager and I was asked to leave the store for spreading false information. I basically laughed at them both, placed all the items on the shelf I was going to buy and left. I only hope the couple buying the dragon listened to me after I left.
