This topic looks almost beaten to death, but I've always found "screaming" to be a tool of the non resourceful. Generally, the goal is to get something, and generally screaming doesn't get you any closer to that goal. That doesn't mean you can't be pissed, or angry, but I've found every time I'm confronted with a situation that's not acceptable talking forcefully, but respectfully goes much further. Customer service people have no real motivation to listen to screamers. They are paid (generally poorly) to shuffle problems around. Many moons ago I worked in a customer service envirnoment and those that were polite were helped first, those who were respectful (if pissed) next, and those that were rude, disrespectful, or screaming were given whatever the opposite of help is. By screaming you are selling the idea that your problems are most important, that they are a lesser person than you (because they can't scream back). It may work once in awhile, but most people will just go out of their way to screw you over. I find it especially appalling when things like weather are taken out on GA's...
