Yes, I vaguely remember that Susie was complaining about people who she served as a waitress in the coffee shop, and the tip they left was all pennies. She was quite vociferous about expressing her dissatisfaction with such rude customers who are so insulting to her with their mountains of pennies. I do not quite see it that way, never having worked in a coffee shop myself. I tend to think that money is money, and even though it would be a conisderable pain to lug around hundreds of pennies, or else take them to a bank where they have one of those automatic coin rolling machines, still money is money one way or another, so moderate your temper tantrum with that comforting thought.
