Debit or Credit?, Widescreen or Fullscreen? A: you're an idiot

A couple of rants for today:

1. When you had me a debit/credit card and I ask you "Would you like to use this as debit or credit?" and you respond "Debit... or credit", it's not answering my question, it's just telling me that you're a dumb ass. I know that it can be used for either function, that's why I asked. Now I have ask the question again: "OK, which one would you like to use?". Thanks though.

2. The widescreen/fullscreen question. I'm fine with having to explain the differences of the two screen formats and explaining their advantages and disadvantages, but not when it goes like this:

Customer: "should I get wide or full?"
Me: "Well, let me explain both formats to you and then tell you why you should get widescreen..... (enter explanation here). So which one would you like?
Customer: "Well, I have a widescreen TV, so does that mean I should get widescreen?"
Me: "Are you fucking kidding me? What do you think it means? GOD DAMNIT PEOPLE"

Am I wrong in assuming that if you know that you have a "WIDESCREEN" TV that the answer to the widescreen or fullscreen question would automatically be answered?

Fucking hell.
