Agricola: Traveling Player?
Traveling Players only becomes really relevant in the full game, when players' Occupations and Minor Improvements may trigger off using it.

So why is it still there in the family game, you ask?  Well, Agricola is a pretty tough game for newbies to "grok" on the first play, or even the first few plays.  The last thing you want is for them to have three Begging cards by the end of the second harvest, and vow never to play this stupid game again!  

By having multiple spaces that just contain food piling up, even the least clued-up player has an obvious way of saving his family from grim starvation at the end of the harvest rounds.  And that's good.  Once they get a bit more experienced, they will turn their noses up at such an inefficient way of turning actions into food... but's that another story, for a later day!
