Probably not the film you're thinking of, but there was a similar scene in Caligula (1979)
. Caligula has ordered the Senators' wives to prostitute themselves to raise money, and upon viewing one particularly unattractive wife, quips to her husband that she's scaring customers away.
As I said, probably not the movie you had in mind, but this relatively famous scene might have 'inspired' the scene in the movie you're looking for.
sorry, I Imdb the Movie connections for Caligula and didnt find what I'm looking for (it doesnt mean that the scene isnt a copy it just means that its not listed)
I do remember faintly it was one of those crime action films. And the fat strippers were so out of place that it was funny. Its not a Chuck Norris or a Charles Bronson action film but this story was quite similar (maybe too similar since I cannot remember the rest of the film)
