Your friend, an avid sports fan, recently purchased a cricket bat from a catalogue. While he was filling out the order form, he noticed the warning, 'Don't send cash!' He asked you, 'Does it seem odd to you that a business wouldn't appreciate receiving cash? You're taking accounting. Don't they teach you that businesses need cash? Why would they say such a thing?' Required:

Tell your friend why you think the business puts this warning in its catalogues, and give him some examples of what might happen if customers paid for their purchases with cash. Explain how cheques and credit cards might prevent this from happening.
