If their eyes glaze over, do the Ron Swanson and get the right one yourself.
I was at a computer hardware store once (back when those existed) and asked for something specific. The kid working there insisted they don’t exist. I told him that I’m confident they do exist because I own one. He went on rambling about how smart and knowledgeable he was, and how he’s certain they don’t exist. While he was talking I noticed there was one sitting on the shelf right behind him. I grabbed it and said “well, for not existing you guys certainly have a good supply of them!”. Then I told his boss that his employees should not tell customers that things don’t exist, just because they’ve never heard of them. What kind of idiot does that?
