How about a barista?
Who are baristas?
A barista is a person dedicated to creating the perfect cup of coffee for the right person.
They blend, brew, taste, test and do everything they can do ensure that your coffee is just right. They innovate, always thinking of new ways to delight you with that ever-flavorful coffee bean.
They are also human, so every cup will be unique — a flavor infused with the humanity of the barista.
However, their humanity is also a limitation. Unlike a coffee maker, baristas can’t just start making coffee whenever you want them to. You can’t just turn on a barista at any time of the day and tell the person to make you coffee.
Also, being human makes the barista imperfect. Unlike coffee makers, baristas cannot be preprogrammed to make the exact same cup of coffee every time.
