Tutorial on how to hire your own sims you made, to work in your Restaurant

@rosemow,
So, in order to go to my own restaurant, on a date that another Sims asks me to go on--I should open my restaurant from home, before going out with that person? I just realized--that is not possible either, because as soon as you accept the invitation to go out to eat, the request starts processing immediately--taking your Sim to the location for the date.
