Or: at some point, one decides to launch the thing.
You are reducing the complaints of an engineer as something inevitable and unimportant, as if it happened in every lunch, and in every lunch someone decided to went ahead, because it was what was needed.
> If you join a consultancy group, and 2 months later quit with the client roster... is it really OK to poach all their clients to start your own consultancy?
If the clients prefer to leave with the then 2 month-old employee, then the consultancy is doing something very wrong.
Or maybe would be disingenuous to think that public transport would cover for all places a car today can go. The world is not only made of urban sprawl.
