A buffet is where you walk around with a plate and pick out exactly what you want to eat. You don’t order anything except maybe a drink.
This is my Plate. I Picked out: Pizza, Pancake, and a Pickle. They all start with the letter P. I made a joke and said, “I’m taking a P-Break!”
Later I got some broccoli and a tart and those didn’t start with the letter P.
