Get the It was a good day mug.
A quick and curt way to end a conversation, putting a thin polite spin on the rude abruptness.

Most uses of this phrase are referencing actor Gene Wilder's portrayal of Willy Wonka in the 1971 movie "Willy Wonka & the Chocolate Factory," where Wonka informs Charlie he has lost the contest because he drank the burp soda, a breach in the contract he signed. "You lose! Good day, SIR!" Wonka screams at Charlie before turning back to his desk.
