Cost of living and Create Food

[mirtexxan]

Hi, would you allow a reduced cost of living for a Cleric with Create Food?
If not, why?
If yes, why?

Is there any social or practical consideration to be made?

Me and my player have agreed to reduce the cost of living to 100$ per week, assuming that he consumes a nice meal per day in the inn (to avoid social issues, and also to make a more believable character that still enjoys "real" food now and then), and the other two he creates himself.
