Model employee or annoying server?

I went to a coffee shop to get a drink and sit down to read. This relatively loud and chatty girl came to ask me what I wanted. Anyways, she was suggesting this and that. Plus, telling me it was $.50 to upgrade to bigger cup, and if I wanted a cookie with my drink. A good model employee I would say.
However, when I sat down not far from the counter to read, her voice just kept penetrating my space. It was high pitched and loud. It didn't help that she was constantly talking. I got annoyed and had to move to a far far corner of the shop. I mean, its not like she did anything wrong, but the noise was just getting to me. Maybe I was being super sensitive.

Here's a thought. Can a person really know everything? I mean there is so much information out there and I don't think its possible for one to fit it all in their heads. I know the mind is a powerful thing, but how much can your brain holds before you need to free up space to remember/learn other things. Plus, the time you need to absorb all information.
Can a computer hold all information then? Maybe if there is enough space and there better be a damn lot.

Gas price is so high. =(...
Just when you think it can't go higher, they prove you wrong. I went from paying $20+, to $30+ to $40+ for a tank. Crazy!
