Restaurant Waiters

[heshamelaziry]

This is too confusing. Could you explain thoroughly please. OA after some discussion.

Assessing the potential earnings of tipped service employees can be difficult. Take as an example restaurant waiters: one might assume that the more customers a waiter has, the higher his earnings will be. But this fails to take into account the degree to which the service rendered might suffer when a waiter has so many customers that he cannot fully devote himself to the needs of any of them.

The flaw in the assumption discussed in the argument to the left refers to doubts about the accuracy of which of the following claims?

A) The earnings of restaurant waiters are approximately the same as the the earnings of other tipped service employees.

B) Restaurant waiters' primary duty is to attend to the need of their customers.

C) The potential earnings of tipped service employees should be measured by examining average earnings rather than the earnings of specific individuals.

D) A restaurant waiter's potential earnings depend on the quality of customers he serves, not on the quality of service he renders.

E) A restaurant waiter's earnings depend in part on how many customers he serves.

first, identify the conclusion of the argument: in this case it's Assessing the potential earnings of tipped service employees can be difficult. .

note that the conclusion talks about tipped service employees in general. however, the premises in the argument talk about waiters specifically. therefore , you would expect the flaw in the argument to be something that highlights a possible difference in a waiter's salary vs every other person who is a tipped employee.

[spoiler]of the answer choices, A makes the most sense. you don't know that a waiter makes the same as any other salaried employee... maybe waiters make more, or maybe they make less. without knowing this fact, then the argument is flawed.[/spoiler]

OA isD. I can't understand the question

[enniguy]

I chose D.

@shadowsjc:
Your explanation sounds convincing. But the question isn't about the flaw in the reasoning but the flaw in the assumption I believe. I am still curious to know why A cannot be the answer here.

As far as IMO D because,
Assumption: "one might assume that the more customers a waiter has, the higher his earnings will be".

This argument has a flaw that not all customers pay equal or comparable tips. As a waiter one needs to serve more quality customers to get more tips.

Why not E.

[enniguy]

Why not E.

Waiters' other income are not the c0oncern in this question. This is specifically about the tips as the first line in the argument puts it.

Well I feel E is the answer. I guess I'm right. If some expert could
