So, I've wondered why there isnt a tag for images wherein a servant and a master are pictured together like the teacher and student tag. It's a type of image that i wish i could easily search for, and there is quite a lot of it. Judging by its popularity I'd think others would appreciate it too. There is so much manga about maids/butlers and their masters, workers and their bosses.
I don't think it'd be hard to tell what images should and shouldn't have the tag. If a maid/servant/butler/female butler/knight/waitress/barista/guard or any other service worker that is subservient to a superior in an image with a person who appears to be their superior, employer or master. You can usually tell this from the clothes of the other person, being clearly of a higher class than them, or if theyre being pampered or serviced by the servant, or if theyre commanding them around verbally or with gestures.
Im modelling this off the teacher and student tag, so images wouldn't have to be of sexual or romantic interaction between the parties, but simply of them being present together.
Below are examples of master_and_servant images and why their roles are apparent, regardless of whatever their canonical relationship may be.
The master being pampered/serviced by servants: https://danbooru.donmai.us/posts/6151502, https://danbooru.donmai.us/posts/3265557, https://danbooru.donmai.us/posts/594231, https://danbooru.donmai.us/posts/31264, https://danbooru.donmai.us/posts/7051079
Servants actively doing duties while a non-servant is idle/not working (implying that they are their master): https://danbooru.donmai.us/posts/6682450, https://danbooru.donmai.us/posts/977415, https://danbooru.donmai.us/posts/5128942, https://danbooru.donmai.us/posts/4943180, https://danbooru.donmai.us/posts/4817861, https://danbooru.donmai.us/posts/4233043
Servants clearly dressed as workers, while counterpart is not a worker, and is clearly of higher social standing, displaying the power imbalance:

Additional reason why i think this tag is needed is because if you are looking for this type of boss/worker image and you type in lets say "maid" and "hetero" to find it, youll get a lot of maids and butlers, maids with men who are obscured or simply nude (not showing if they are their superiors or not). Same goes for if you were to look for "maid" and "yuri", you get mostly maidxmaid artwork. You'll find master and maid in those searches too, but it'll be harder for a person with this preference to find it, and I'm confident they exist.
This whole series is a pretty good example of people enjoying this specific dynamic https://danbooru.donmai.us/pools/20108.
