At Home Depot, they will always answer your questions and suggest products, although they usually know nothing, on the rare occasions when I have had to go to one, I will ask them questions, and am usually amazed at the stupid answers, but they are always confidently given.
They never just say, "I don't know".
They’re exactly the same way at Best Buy. Someone can go in there needing a device to achieve some sort of solution or goal, and one of their idiot employees will have them leaving with a $700 cart full of ‘stuff’, while a simple $15 part would have sufficed(I’ve seen that happen MANY times to people I do IT work for).
I suppose that’s a GREAT business model, assuming everyone is ignorant.(more so than the store employees)
