What I observed that I think could be harmful:
There are many white looking, male bartenders depicted in the images.
Why I think this could be harmful, and to whom:
I think this could be harmful because it may cause more stereotypes that bartenders are white looking males since there are female bartenders and bartenders of color as well.
How I think this issue could potentially be fixed:
Include more women and/or people of color.
This observation is significant because this might discourage females from pursuing this career. It would be also interesting to include different types of bartender outfits and further diversify the images from the stereotype.
