What him, showing off? Don't be silly. Is he really the kind of demon to stand around tempting people from doorways? He was the epitome of innocence, not even rising to the challenge of telling Aziraphale what sort of tips this particular waiter cared for when he delivered the tray. He just looked at the angel enjoying his meal and held back the words with a smirk.

"I would't know. I took one look at the Shrimp Aspic and left it all well enough alone."

The soup had been his first actual meal in this world and it had left him with a horrible, diabolical thought.

"I suppose we'll have to become friends with him, Sylvando. Invite him over now and then so we can enjoy more of his cooking."

Because clearly using some one was the best reason to become their friend. Demon priorities.
