My patience is not compatible

People kill me with the words they use when speaking to a computer salesperson. Words like gigas, tetrabyte, refering to the computer as a modem, and the worst of all compatible. Now someone might be sitting here saying, "Now Akmed, compatible is a perfectly fine word to use when refering to computers. Such as, will my software be compatible with this? Is my printer compatible with this?". Oh I know, those are great questions. I'm talking about when a person is looking at a computer and asks me to show them a computer that is compatible to the one they are looking at. The first few times it happened it was "cute" but, you would not believe how many times this happens in a single day. It has gotten to the point that it bugs me so bad that when a customer asks me to show them a computer that is campatible to the one they are looking I always say to them "I don't know what you mean" then they tell me they want to look at one similar and I respond with "OH! You mean COMPARABLE!" Then the customer will get irritated with me and say "yea that's what I meant"...oh I'm sorry you dumbass for being oblivious to what you are talking about because of your atrocious use of the english language. Don't get mad at me for being intelligent and not understand what you're saying, get mad at your 3rd grade english teacher. They are the one that's the jackass for not teaching you how to speak correctly. You do not have to know a thing about computers to know how to use the word compatible correctly. And the salesman is the one that doesn't know anything about computers? Maybe if you knew what the crap you were talking about and made logical sense we would be able to help you. "I need a USB". Ok...continue..."I NEED A USB!". Ok, you yelling at me isn't going to change the fact that you are an idiot. Maybe next time you ask me if windows comes on the computer, when you are actually refering to microsoft office, I will just tell you yes instead of compensating for your stupidity.
