I interjected and possibly cost them sales on tank stand combos and expensive fish and corals. Not right to tell someone they can buy a 2k tank, dry rock for it, water, all this expensive stuff to go in it and it will live when you set it up that day and put the stuff in it. That is just not right, so I opened my mouth, nicely, and suggested to their customer against it and showed them a tank cycling thread and a thread for what happens when you do things like what they were trying to sell.
Now I admit that was wrong, own it and it is mine to own. I was in their place of business, so shame on me. The difference is civility. There are ways to handle things and ways not to. But either way, I was wrong, should have walked away, wrong again, and in this instance, wrong for running my mouth instead of walking away. No ones perfect lol.
