Grocery Store

Adam and Angie were playing grocery store.  Adam was the clerk and Angie was the shopper.
When she checked out Adam took each item out of the basket and instead of scanning each item or putting in a price on his cash register he used the scale for each item.
This was the conversation.
" This corn is as long as a carrot."
"This ball is as long as a blueberry."
"This car is as long as a pencil."
"This spaghetti is as long as a carrot too."
