ANOTHER DAY, ANOTHER DOLLAR
James Cash is a very rich man – in fact, he's a multimillionaire. He is thirty-five years old and lives in a
mansion in the country. He is the chairman of a big
company.
Every day he has breakfast in bed. He usually has
boiled eggs and champagne. He makes phone calls and
reads the newspapers at breakfast time. Then he gets
dressed. His servants help him. He always wears a smart
suit to the office.
At seven o'clock his chauffeur drives him to his
office. He has business meetings every morning. Every
afternoon he looks at the sales reports. Sales go up every
year because business is good.
In the evenings he likes to entertain important
business clients. They often go to his favourite night club,
Madame JoJo's. They have dinner, drink champagne and
watch a cabaret.
At two o'clock in the morning his chauffeur drives
him home. He goes to bed half an hour later, and dreams
about sales figures. James is always exhausted. The next
day is exactly the same. Would you want a job like his?

1. ANSWER THE QUESTIONS:
1. Is James Cash rich or poor? What is his financial status?
2. What does he do? What is his position?
3. Is he an old man? How old is he?
4. Does he live in a flat? Where is his mansion located? Where does James Cash
usually have breakfast?
5. What does he usually have for breakfast?
