Is there a "stupid" dialect?

Yesterday I had a conversation with the most unhelpful tech person I've ever talked to. And I knew it was going to be a bad conversation just from his voice. He had a "stupid" voice.

Now, as soon as I had this ungenerous thought, I dismissed it: No, no, I told myself; you're being judgmental. This is probably just an area dialect and you shouldn't be so judgmental.

Except that I couldn't identify the dialect, and he really was genuinely stupid.

So here was the situation: I bought a new router (a D-Link) the other day, and it didn't work. All the lights came on, but my computer couldn't detect the router. So I called up the D-Link help desk and got the guy with the stupid voice.

After asking me all the standard questions--my name, the model of the router, etc.--the man with the stupid voice told me we would now run through a verification process to see if the router really was malfunctioning. First he wanted to see if I had any internet connection.

Yes, I do, I told him. When I plug the computer directly into the modem, it works. It's only when I plug it into the router that I don't receive a connection.

At this point he interrupted me.

"Ma'am," he said (belligerently, I thought), "You need to listen to what I am telling you. You need to go through all the steps of the process that I am telling you. We are here to help you. You need to understand that we are just doing the best that we can." (There was more to this speech, but I can't remember it. It was basically more of the same.)

I was a little taken aback--after all, I thought I HAD been following his instructions--but all I said was, okay--I'm listening. What do you want me to do?

Again he told me we needed to see if I was getting any internet connection. Again I told him I was indeed getting one--that I was on Firefox right at that moment. Again he berated me for not listening, and told me this time that if I couldn't follow directions better, then he couldn't help me any further.

So it was looking pretty bad, but still, giving up would have meant another half hour on the phone with a different technician. So instead I asked, very slowly and carefully, "Sir, do you want to test my MODEM first, or my ROUTER? Which would you like me to connect my computer to first?"

But alas. One should never suffer fools. All I got was another harangue about how I wasn't listening--serves me right for trying.

So I gave up. It was clear that the man with the stupid voice didn't know anything at all about routers, and that he somehow thought that convincing me that I was the problem would buy him one more day of employment. So I asked for another technician--who found--voila!--that my router was indeed malfunctioning and needed to be returned.

And it only took me two hours on the phone to find this out.

But I ask, how is it possible for a technician to work for a major router company if he doesn't know the difference between a modem and a router?

And IS there a stupid dialect? Because I swear his voice dripped "stupid" out every syllable.
