I just wanted to try reading it because it happened to be a free content on EBJ (vol 1 only). But thank you for continuing this! I'm curious.
Honestly, I don't really recommend stories about bartenders. Indeed, not many are offered because they always play with complaints and whatever the environment around the customer works makes them stressful. But just like Bartender manga, there is an interesting part when viewed from the social side without any strange performances to attract interest from the strangeness.
