I am so fucking pissed

I am so fucking pissed off right now, I could kill someone.  I can understand not being incredibly happy about paying for the extra parts, but those are the required parts to make the fucking thing work...its a GM, yell at them about the stupid anti theft system.  What I don't understand is walking in a noticing its a different guy standing there and claiming that the guys earlier didn't tell you about those parts, thats just plain wrong.  You sir are a little bitch and you better hope you don't meet me on the fucking street or need more work done on that car.  You have actually prompted a complete policy change and  I am considering a large sign with your name on it attributing the policy change directly to you so everyone can see how much of a shady little piece of shit fuckwad you are.  Enjoy.
