Yeah, I went buy a tablet and I wanted a specific form factor. So when the retail worker asked me what I wanted, I told them the specific product. They mentioned other models that were newer, faster, better, etc. And I simply told them that I was looking for one I could fit in my hand by basically palming it. (Being in person, I could just hold up my hand and say "hold it like this"). Once I explained that, I was able to get what I wanted with no more questions. Now that they knew why I wanted what I wanted, they also knew what information was relevant to me. And I had already chosen the best model they had in that form factor. Communication should be simple, direct, and complete. That's where I don't care if I "look stupid". I'll go over basics if there's a chance someone doesn't know the basics. Because you can say, "Oh I'm aware of X", but if you aren't and I assume you are, you may be too embarrassed to bring that up because you're afraid I think you're stupid if you don't know it.
