I was also wondering what kind of plot it could have, but reading you, I understood that it goes beyond serving a drink, they explain it and also try to show what is behind the customer.

I hope never to fall in a bar for reasons of distress, if I go there it will be to have fun haha but I liked that it invites to empathize with those who are going through a bad time and looking for a place like this to rest 🙏
