But his reply was even ruder. “You seem to think you have a God－given right to pollute your neighbors' atmosphere,” wrote John Ferriday of Paramount Airways. 　　(a)Maureen said, “I only found out about it when I was checking' in. I'm a nervous flyer so I lit a cigarette during the flight. A steward asked me to put it out, but I said I wanted to carry on as there was no rule against smoking on the plane.” She was just finishing her cigarette when the pilot arrived. 　　(b)“I've never seen such an unpleasant letter.” She said, “I don't think I'll ever fly again. But there was a funny side. Maureen explained, we were offered duty－free cigarettes from the stewardess on the plane!” 　　(c)Mr Ferriday went on, “Believe me. You don't have the right especially when you travel on my planes.” Maureen and her husband Michael were moved to Paramount just before they left Portugal. But they were not told of the company's no－smoking policy. 　　(d)“He was loud and rude,” said Maureen. “He said if I lit another cigarette he would land the plane at Bordeaux and hand me to the French police.” 　　Later, from her home in Mosley, Birmingham, Maureen wrote to the company and received the rude reply. 1．The latter part of the story is in wrong order.
