Read the excerpt from sora and yuma’s debate.
sora: when shopping, using the self-checkout essentially qualifies customers as employees. the customer must scan items, bag products, and enter codes. these are the same basic tasks required of a cashier. so, why does a store need both of them? yuma: the duties of a cashier are far more involved than self-checkout. self-checkout is a luxury offered to busy customers in a hurry. however, this does not qualify a customer as an employee. what is the most likely reason that sora lists the activities of customers going through self-checkout?
a. to prove the claim that customers are trained enough
b. to get paid for self-checkout
c. to prove the claim that self-checkout is difficult
d. to prove the claim that cashiers’ duties are as simple as self-checkout routines
e. to prove the claim that self-checkout is eliminating jobs
