McDonalds: Address to a Big Mac

Your classic design is a world-changing feat:
Reclining with grace on a three-piece bread suite -
Two duvets of cheese; two pure discs of meat,
Your sauce devine.
Don't discard gherkins too good not to eat,
Put them on mine.

Teenagers who did not learn much at school,
Lovingly grill you whilst watching us drool,
Thank god in this world so demanding and cruel,
You have a flourish,
You wait in the chute for me, starting to cool,
Then partly nourish.
