Then you are hiring the wrong people for the kind of coffee shop you claim to desire running. There are plenty of people who enjoy coffee enough to make a career out of it even if it's for a few years. You are pitching this evolved, pay every one a fair wage, this is a real place to work that's super cool, and then treating them like it's some chain. It's transparent. You don't expect them to work with you longer then a couple months. You want customers to track whether employees are doing good or not trying to create some BS KPIs or whatever and then use that to incentivize your employees. Everything you write in every one of your posts demonstrates that you seem to miss the entire point of a coffee shop. It should be a cool place to relax and read or work or meet friends while drinking coffee.
