Temura 23: When and Where is a Gift Consumed?

In Vayikra 6:9, we learn "And that which is left thereof shall Aaron  and his sons eat; it shall be eaten without leaven I a holy place; in the court of the tent of meeting shall they eat it".  Out Gemara quotes a barita to explain that passage:

Why does the text state "They shall eat"?  This teaches us that if there was only a small quantity of the meal offering gate priests may eat chullin, unsanctified, food and teruma, priestly offerings, with it in order to make a full and satisfying meal.  What is the point of the expression, "They shall it eat"?  In order to teach us that if the quantity was large the priests must not eat chullin or teruma with it, in order that the meal offering should not make an achila gasa, an over-sated meal.

Rashi says that chullin is easy to bring to the Temple court as one can eat chullin outside of the court and the continue the meal offering in the Temple court.  Tosafot say that there is no restriction when bringing an object into the Temple court as long as no service is performed with it.  

We learn that achila gasa usually refers to eating ravenously; without etiquette.  As well, if someone continues eating after s/he is full, eating becomes unpleasant.  That action does not meet the Jewish definition of eating.
