Who said "You've been dining out on <someone> for years - you must be hungry"?

[LaMarschallin]

And to whom about whom?
Something made me remember this question/statement and it's driving me mad that I can't remember the people it concerned. I think it was a celebrity interview and the "someone" mentioned was famous.
It was phrased as the title suggests; it could have been reversed, like "You must be starving, you've been dining out on so-and-so for years" and implied that the person being interviewed was only really famous because of their connection with the person mentioned.

Eta Google has not been my friend in this case.

I feel like I heard it recently but as a retold anecdote - maybe a talk show?

I can remember Prince Harry saying it very rudely to John Travolta at a daft ceremony for an aviation award in America. Travolta presented him with it.
The thing is when Princess Diana first became famous, Travolta was one of the most famous people on the planet. When he got Diana up to dance in the White House it made headline news as she loved to dance - and he really could dance.
To my memory it’s not something Travolta dined out on, more something he was asked about.
It was a really rude of Harry to say it, it got passed off as banter, but it was not remotely funny.

May be this?

I remember that, @PetulaGordeno , and agree it was really crass and made Prince Harry look silly.
It's kind of you to reply, but the one I'm thinking about happened longer ago and the person accused of "dining out" was actually a minor cleleb which made a real burn (unlike Harry and Travolta as Travolta actually is a big star who's achieved a lot and that's not what people first think of when they think of him).

I felt the comment I'm trying to remember was up there with Mrs Merton's "What made you marry the millionaire Paul Daniels?".
And it definitely mentioned the person being hungry/starving/something like that because it was such on old story they were dining out on.

You’ve got me thinking now. And God bless Mrs Merton what a genius she was.
I keep reading it in a sort of David Niven voice it sounds very 1970’s, late night chat show where everyone smoked and drank whisky.

Not sure about the original quote, but Russell Brand said a variation of it to Bob Geldof around 15 years ago?

”Bob Geldof knows a lot about famine, he’s been dining out on [something] for years”

I was under the impression that phrase referred to an action rather than a person so [person] is dining out on [action, occasion or event] as they keep talking about it because it makes then feel important or interesting. My Mum claims that i could dine out on my sixth form school being called Sexey's and that i am descended from William the Conqueror (along with half the country)!

It makes no sense? Why would you be starving when you've been 'dining out' constantly. Surely it should say 'I'm surprised you're not the size of an elephant?' or something?
'You've been eating loads so you must be really hungry'?! They didn't think that one through I don't think.

Russel Brand about Bob Geldoff knowing all about famine( Live Aid) as he's been dining out on Don't like Mondays for years

That's what I thought!

Sounds like Joan Rivers or someone to me, but I haven't unleashed my google-fu.

Dining out on the same thing (Don't like Mondays) for 30 years, hence it is running out of steam/food

It's a confusing one all right, is it that you've been dining out/telling the story for so long that you've used up all the attention and interest so now you must be starving?

Anyway, this is a great example of how Google search is utterly enshittified now.
Instead of just searching for a phrase, it insists on trying to guess what you mean and turns up all sorts of nonsense about chefs and dining.

I guess it's also not been quoted very much in webpages, or at least not directly attributed to someone.

Do you think it was a snarky interviewer like Joan Rivers or Dennis Pennis, or a more random conversation?

That's the very one! Thank you! 💐

Thank you and 💐 to you too, @JoleneJoleneJoleneJoleneJolene for supplying the Don't Like Mondays" bit and for explaining the usage of the phrase, as used in the quote, with:

You're dead right.
All I was getting were suggestions of "restaurants near you" or explanations of the phrase.

Thank you to everyone who posted - I'm really grateful and can stop fretting about it now.

(Having previewed, I can now keep my brain active by wondering why adding an asterisk at the beginning and end of a quote gives bold in one case and italics in the other 🤔)
