One man's meat, another man's gravy.

A nice twist on one mans meat, another man's poison. Where neither option is that bad. Invites thought , laughter and useful for pub banter.

Originated in the pubs of South London in the 1940s.

I don't know Bill, I don't know what he sees in her.
"One man's meat, another man's gravy."
Long pause...
"But which is better? Meat or gravy?"
"Exactly."
