A  little boy went to a telephone booth which was at the cash counter of a  store and dialed a number.
The store-owner observed and listened to the  conversation:

Boy                : “Lady, Can you give me the job of cutting your lawn? 
Woman         : (at the other end of the phone line) “I  already have someone to cut my lawn.” 
Boy                : “Lady, I will cut your lawn for half the price  than the person who cuts your lawn now.” 
Woman         : I’m very satisfied with the person who is  presently cutting my lawn. 
Boy                : (with more perseverance) “Lady, I’ll even sweep the floor  and the stairs of your house for free.
Woman          : No, thank you.

With a smile on his face, the little  boy replaced the receiver. The store-owner, who was listening to all this,  walked over to the boy.

Store Owner       : “Son… I like  your attitude; I like that positive spirit and would like to offer you a  job.” 
Boy                       : “No thanks, 
Store Owner       :  But you were really pleading for one.
Boy                       : No Sir, I was just  checking my performance at the job I already have. I am the one who is  working for that lady I was talking to!”
