Well, I guess that would really depend how many people I'll be meeting!

For example, if I'm cooking for eight, then only sixteen persons' worth of food will do.
I mean, I'm not going to let people go without seconds! ... Or maybe even thirds.

Twenty-four person's worth of food...
Are there enough tables at the cafe to hold that many dishes?

[... He seems completely serious about this. He doesn't even know how many people he'll be meeting, so hopefully it's a lot less than what he's imagining -]
