This is quite interesting once again Mofu-san, after reading about the maid's bar , I can slowly picture how this is starting to look like. I can see the staff being different races and different ages from the plump, milf, maids with lots of experience, to the younger more adorable, clumsy, nervous girls. And even the tough, cool onee-san maids that get annoyed from customers that try to grab their ass etc.
I hope their maid outfits are really cute but really erotic. Kinda like a Hooters style restaurant where they tease you,but as the rule goes" you can look but can't touch"
And sometimes the maids might tease certain customers too much and some customers loose control and try to blow off steam with the one of the maids in front of everyone, but in order to keep order in the bar, sometimes the customers may need to be thrown out. Which is where the tough tomboy maids come in. This could be a popular spot I can see in the village.
Another question, are there any plans for the village to have a brothel? Something similar to Ishuzoku Reviewers could be interesting. Probably an older head mistress(an expert with years of service experience) that runs the place, she could have really beautiful makeup and smokes from a fancy pipe. Nene could work there or even be a customer and have quests from the different staff and get favors/rewards for different services or outfits.
