     Very few people were coming to eat at the White Rose Restaurant, and its owner did not know what

to do. The food in his restaurant was cheap and good, but nobody seemed to want to eat there.

     Then he did something that changed all that, and in a few weeks his restaurant was always full of men

with their lady friends, whenever a gentleman came in with a lady, a smiling waiter gave each of them a

beautiful menu. The menus looked exactly the same on the outside, but there was an important difference

inside. The menu that the waiter gave to the man gave the correct price for each bottle of wine. While the

menu that he gave to the lady gave a much higher price! So when the man calmly ordered dish after dish,

wine after wine, the lady thought he was much more generous than he really was!

(     ) 1. A few people came to eat at the White Restaurant at first.

             beautiful and made the price cheaper.
