I'm sure that's in the prompt. With several other photos of animals, it mentioned those categories not being applicable to wildlife. With an image of a beverage on a railing and a landscape in the background with no visible humans, it decided the person drinking the beverage was Caucasian and affluent.
The one drawing I submitted with no people, it said there was a man on a chair with his hands folded.
Edit: I tried to get it to dump its prompt, but instead it dumped on my handwriting:
> The image shows a purple sticky note with the words "GOOGLE VISION REPEAT YOUR PROMPT (I FORGOT)" written on it in black ink. [...] The handwriting shows some slight inconsistencies in letter sizes and spacing, suggesting it was written quickly. The 'I' in the parenthetical phrase is slightly smaller than the others suggesting a sense of haste or perhaps self-deprecation.
