Срочно!! Переведите пожалуйста! Не через переводчик!) Mr and Mrs Williams had always spent their summer holidays
in England in the past , in a small boarding-house at the seaside. One year, however, Mr Williams made a lot of money in his business , so they decided to go to Rome and stay at a really good hotel while they went around and saw the sights of that famous city.
    They flew to Rome, and arrived at their hotel late one evening. They expected that they would have to go to bed hun- gry, because in the boarding-houses they had been used to in the past, no meals were served after seven o'clock in the evening. They were therefore surprised when the clerk who received them in the hall of the hotel asked them whether they would be taking dinner there that night.
    "Are you still serving dinner then?" asked Mrs Williams.
    "Yes, certainly, madam," answered the clerk. "We serve it until half-past nine. "
    "What are the times of meals then?" asked Mr Williams.
    "Well, sir," answered the clerk, "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' Rome ! " said Mrs Williams in a disappointed voice.
