A priest (牧师) had to give services in several churches every Sunday, and one of them was in the center of a big city where there were lots of offices, but where very few people hived. As a re- suit, hardly anyone ever went to this church on Sunday. The priest used to go there in a taxi, and one Sunday he arrived as usual and told the taxi-driver to wait while he read the service. When he entered the church, he found that there was only one man there, so he inquired whether he would be willing to have a shortened service.
"No," replied the man firmly and without any hesitation, "I' d like to have the full service, without omitting anything.”
When the priest said the last prayer(祈祷) and left, he discovered that the man in the church had been his taxi driver, whose meter (计程器) had been adding up the expense throughout the service.
How did the driver possibly go into the church？

A. He went with the priest.
B. He followed the priest.
C. He went through another door by running.
D. He went into the church faster before the priest while he did not notice him.
