"I have the same feeling about rats," replied Pickles, "but it would never do to eat our own customers; they would leave us and go to Tabitha Twitchit's."
"On the contrary, they would go nowhere," replied Ginger gloomily.
(Tabitha Twitchit kept the only other shop in the village. She did not give credit.)
Ginger and Pickles gave unlimited credit.
Now the meaning of "credit" is this—when a customer buys a bar of soap, instead of the customer pulling out a purse and paying for it—she says she will pay another time.
And Pickles makes a low bow and says, "With pleasure, madam," and it is written down in a book.
The customers come again and again, and buy quantities, in spite of being afraid of Ginger and Pickles.
But there is no money in what is called the "till."
