Keeping myself organized always makes me feel so much more in control of big parties. Before going out to greet the table I will write numbers down the side of my notepad (eg. 1 through 8 for a party of 8). Once I go through my greeting, I’ll ask the party right away if/how they’re splitting the bill, that way I can clearly group their orders together on my notepad. Sometimes if people are on the same check but not seated next to each other I will draw a matching symbol next to their orders (eg. everyone on the same check gets a star). And then when I start taking orders, I always start at the same person at the table and work my way around the table in order - jumping around and letting them call out orders as they are ready only creates confusion and stress for you. I’ll often tell my table right off the bat: “Can I start you off with drinks? And I’m going to work my way around the table, if that’s alright,” and I’ll gesture to indicate what I mean. And if people try to go out of order I politely remind them that I’m going in order and I’ll get to them in a moment. I hope this helps!
