Which of these does an appropriately cautious reading of a receipt entail? I. Making sure that the items charged are the same as the items received. II. Asking for a second copy for your records. III. Checking to see if all of the discounts were applied properly.

An appropriately cautious reading means checking that the receipt accurately reflects the purchase. Compare the charged items with what you received, and verify that any discounts were applied correctly. Asking for a second copy may be useful for recordkeeping, but it is not part of reading the receipt cautiously. Therefore, the correct choice is I and III.
