“Our House” restaurant is eliminating table-service from its casual dining restaurant in favor of prepared dinner boxes. The restaurant already fills every available seat during its operating hours, and the change to a dinner-box style will not reduce the available seats. Nonetheless, the restaurant's management expects revenue to increase as a result of the switch to the prepared dinner boxes without any concurrent change in revenue per customer or operating hours.
Which of the following, if true, provides the best reason for the expectation?
(A) One of the dinner boxes takes up less storage space than the space taken up by one of the large dishes typically used when serving table-service customers
(B) Diners eating out of a dinner box typically do not linger over dinner as long as diners who are served via standard table-service.
(C) Since the restaurant will eliminate table service for only part of the restaurant, it can continue to accommodate customers who do not wish to eat out of prepared
dinner boxes.
(D) Few diners are likely to avoid the restaurant because of the new dinner-box style.
(E) The restaurant eliminating table-service would otherwise have to hire new waitors and waitresses at a greater expense due to new city regulations on wage
Original Source: Practice Pill PlatformThere is a change in the way food is served.
The restaurant fills every available seat during its operating hours.
No of seats stay the same.
Revenue per customer will stay same (per person cost stays same)
Operating hours stay the same (the restaurant still works from say 7 pm to 11 pm)
Expectation: Revenue will increase.
Think about it - it is odd, right. Only the style of serving food has changed. The cost of food is same and the operating hours are same. Why would the revenue increase then? Only if more people are served in the same time. How can more people be served? If each person spends lesser time, more people can be served in the same operating hours (it fills every available seat in its operating hrs. Think of a queue outside the restaurant till it closes).
(A) One of the dinner boxes takes up less storage space than the space taken up by one of the large dishes typically used when serving table-service customers
Table space is irrelevant. Number of seats stay the same.
(B) Diners eating out of a dinner box typically do not linger over dinner as long as diners who are served via standard table-service.
Correct. People spend less time over food so turnaround time decreases. Till now, every persons pent 1 hr for his dinner so 4 people were served in 4 hrs at every seat. Now people get done in half an hr so 8 people are served in 4 hrs at every seat. So more people are served.
(C) Since the restaurant will eliminate table service for only part of the restaurant, it can continue to accommodate customers who do not wish to eat out of prepared
dinner boxes.
Irrelevant. Doesn't tell us why revenue will increase.
(D) Few diners are likely to avoid the restaurant because of the new dinner-box style.
At best it suggests that the revenue will stay the same with dinner boxes. Doesn't tell us why revenue will increase and not stay the same.
(E) The restaurant eliminating table-service would otherwise have to hire new waitors and waitresses at a greater expense due to new city regulations on wage
Irrelevant. We are talking about revenues only.
Answer (B)
