Mr. and Mrs. Smith always spent their holiday in London in the past, staying in a small inn at the foot of a hill. One year, however, Mr. Smith made a lot of money in his business, so they decided to go to New York and stay at a really good hotel while they went touring around that famous city.
They flew to New York and arrived at their hotel late one evening. They expected that they would have to go to bed hungry, because in that small inn in London, no meals were served after seven. They were therefore surprised when the man who received them in the hall asked whether they would take dinner there that night.
"Are you still serving dinner" asked Mr. Smith.
"Yes, certainly, sir," answered the man. "We serve it until haft past nine."
"What are the meals then" asked Mr. Smith.
"Well, sir," answered the man, "We serve breakfast from seven to half past eleven in the morning, lunch from twelve to three in the afternoon, tea from four to five. And dinner from six to half past nine."
"But that hardly leaves any time for us to see the sights of New York," said Mrs. Smith.

[A] thought she would have plenty of time to see the sights
[B] was afraid they would have no time to travel around New York
