to believe that it is likely that
(A) some celebrities come to the Hollywood to be seen, and so might choose to
sit at the tall tables if they were available
(B) the price of meals ordered by celebrities dining at the Hollywood

(C) a customer of the Hollywood who would choose to sit at a tall table would
be an exception to the generalization about lingering
(D) a restaurant's customers who spend less time at their meals typically
order less expensive meals than those who remain at their meals longer
(E) with enough tall tables to accommodate all the Hollywood's customers
interested in such seating, there would be no view except of other tall tabl

想请问这题的D选项

脑袋转不过来 麻烦指教 感谢~~~
