The Grammar of a Dinner

let's have chicken for dinner.

somewhere else, someone else utters:
let's have john for dinner.
we are alarmed by the latter
but a dinner, too, has its own grammar
& we are assured by grammarians
both utterances are in order.

john, + animate, + human,
couldn't be passed off as repast.
chicken is + animate, - human,
& can end up in any oven.
if we combine the items of grammar
the way things in cooking are,
we would then have:
let's have chicken for john for dinner,
let's have chicken for dinner for john,
let's have for john chicken for dinner,
let's have for dinner for john chicken;
but probably not:
let's have john for chicken for dinner,
let's have for dinner john for chicken.

john is a noun holding knife & fork.
chicken collocates with the verb eat.
grammarians favour such words
as delicious & john eats happily,
but in a gastronomic dinner
taxonomic john isn't to eat deliciously.
