Kalle works part-time in a bar in Berlin and is actually quite happy with his job - only the scheduling annoys him.
This is done with notes, pencils and many, many (really very many) phone calls, which costs everyone involved a lot of time and nerves
And as it happens when hip big city meets young, ambitious heads, great things are created (sooner or later). So he teaches himself programming and develops a system that makes short, simple processes possible and simplifies the planning of personnel for "his bar" - the forerunner of Easypep. (a real, yes, you could say, milestone for digital personnel management. ).
