(Mishnah): A worker may eat pumpkin even worth a dinar or dates even worth a dinar.

R. Elazar (ben) Chisma: A worker should not eat more than his wage.

The Chachamim permit it (i.e. eating more than his wage). However, they instruct a person not to be gluttonous thereby preventing himself from being hired by others.

A person may make a stipulation that he will not eat, in exchange for a higher wage. He can also make this stipulation for his adult children, his adult slaves and for his wife as they all have 'daas' - 'understanding'.

But he cannot stipulate for his young children nor for his young slaves, since they do not have understanding.

(Gemara) - R. Elazar ben Antignus quoting R. Elazar bei R. Yanai: This shows that a worker may eat more than his wages.

Some say that R. Yochanan said from R. Yanai: This shows that a worker may eat the first and the last clusters (even they were the only clusters growing).
