Can anyone give me a briefing on what to expect in my new job as a waitress?

I worked in foodservice at a hospital so I am familiar with how to treat customers (plus, there are tons of guides for that online).

What I need to know involves the mechanics. I was hired on the spot at a new sushi restaurant when I went to fill out an application, and was only told the dress code and to come in at Monday at 5:30, so I'm getting the impression that this job might not have the most concise and organized structure.

I need to know about how I report tips and all that, what I do with the plates when I clear them, how do I turn in orders, etc. Hopefully I'll be trained, but the only thing I'm optimistic about is making money. Like I said, they seemed a bit disorganized, so I'm worried that I'll get dumped straight into this.
