Rep: Hi, My name's Jeff. Welcome to 3fone2-mobile, how can I help you?
Me: Hi Jeff, my names Gullible Geek, and I have a couple of grand I'd like to give you.
Rep: I can help you with that Mr Geek.
Rep: What would you like in exchange for the loot.
Me: I'd like an iPhone 4 please, if that's alright, pretty please.
Rep: I'm sorry, my company are so badly organised we can't take money from you today. Please sit in front of your computer waiting for an email and call us back when it arrives, along with thousands of other customers.
Me: Why can't I just order it now and we can all get back to more important things?
Rep: Because you can't.
Me: Erm, that's a bit silly isn't it?
Rep: Is there anything else I can help you with today.
Me: Erm probably not.
