You have to pick:

Is this _all_ that I can eat? Or is this more like "congratulations, you've won a lifetime supply of free bread sticks!" And I can just go somewhere else if I want to eat something else?

I think that the bread sticks are the only thing you can eat. But they're unlimited....

Being a centaur in the modern age would be kinda difficult, how would i fit through doors, or buckle in on a plane, and peeing would probably be real difficult.
