The Hold Up - S10-E3
Plot hole: When the robbers come onto the floor and go into Mr. Rumbold's office, the staff suggests calling the police, only to be told by Mr. Harman that the only outside line is in Rumbold's office. This, despite the fact that there have been numerous occasions throughout the series where characters made and received personal calls on the department phones (Mrs. Slocombe calling her cat, Mr. Humphries calling his mother, etc).
Answer: In minstrel shows there was also a stereotype of black men preying on white women, so that's probably why she was not in black face. Also, Mrs. Slocombe is in blackface because she is an older, stout woman and she fits the "mammy" stereotype.
Not the person who did this post. Whoever said that back in the day is so ignorant.
I've never heard that before, that people did blackface because black men were preying on white women. It makes white women seem dumb, and we were told that it was done to make fun of our big lips and our colour as jiggaboos. It had nothing to do with preying on white women.
