New Job

I started my new job today,and it's my first 'real' job even though I'm 19.It's been really hard finding employment so I was stoked when I finally got a call to say I have a job...but man,I hope I don't let myself down.
I'm working in a Pizza Hut delivery place and they make it seem so easy.But all the different crap on the computer system and trying to work through it fast whilst placing an order...it'll take some time...but I'm so afraid that they're going to think I'm stupid or something!

And god help the people when I start making pizza,haha....cause I ain't that great in the kitchen.But I'm determined to stick it out...it'll come to me eventually,right?

So...does anyone have any funny stories about their first day working or any advice for me?
