Organizing Your Server Book
Main thing I would change here is how I handle apps/ desserts.
I write those to the side next to the seat number of the person that ordered it. Then when the table inevitably asks for checks to be split up, I can easily assign the orders to whoever ordered them.
Other than that, this is my tried and true method. I see people with complicated server books full of lines and boxes and thin little sheets of paper that start getting ripped... no sir. Not in this house.
I use proper card stock, go to home depot, have them cut up like 100 sheets, and I'm good for a year.
Final note: I consider my memory to be excellent - but I still write everything down always. You know why? Because committing orders to memory takes up unnecessary space in my mind that I'd rather devote to handling my section and chit chatting with coworkers that I like.
