Go for it.
I hope people eventually understand that when they are rude ignorant assholes that I am doing the BARE minimum of what I have to do. I will play completely by the book.
I am customer service manager in my company and I feel your pain! Its amazing what I will go out of my way to do for someone who is nice and when they aren't its like "Ok Hold let me see what I can do" Place on hold, tap fingers on desk, pick up minutes later "I'm so sorry but I'm afraid that this is the best we can do". If you are going to be a dick either way then what does it matter?
