Jack Whitehall got fired from a bar job after he called a customer a "****".
The 30-year-old comedian surprised after-work drinkers at London pub The Wigmore this week when he turned up with Grey Goose Vodka and delivered an impromptu stand-up show during which he revealed the hilarious anecdote.
He said: "I did once work behind a bar, but I got fired because someone clicked their fingers at me, and I called them the c-word.
"Let\'s hope that doesn\'t happen again, it might put a bit of a dampener on the evening. We\'re here to Live Victoriously and have a wonderful, spontaneous, exciting night and I am well down for that."
To launch the new Grey Goose brand platform \'Live Victoriously\', Jack and Clara Amfo turned an average Tuesday night (16.04.19) after-work drinks into an unforgettable memory, with the surprise performances.
The radio DJ treated the unsuspecting crowd - who also enjoyed a selection of cocktails at the event - to a set of her own.
The vodka brand also took over New York City with Jamie Foxx, \'Shrill\' star Aidy Bryant and \'Saturday Night Live\' comic Colin Jost all treating punters to surprise comedy performances.
Jack\'s own routine comes after he recently revealed how he "absolutely died" on stage in front of Prince Charles during a show in honour of the 70-year-old royal\'s annual staff Christmas party.
The \'Fresh Meat\' actor previously explained: "I walk out, first thing that\'s weird is that they\'re sat in the front row, Charles and Camilla, in thrones... Also, don\'t sit in the front row because that\'s your get-out-of-jail-free card as a comic, [you pick on the front row], you ask them what they do for a living... I can\'t ask Prince Charles what he does for a living!
"[It was a] small room, maybe 40 people, all of my material was terrible... I absolutely died."
