回答题。An embarrassing experience
It was the small hours of the morning when we reached London Airport．I had cabled London from Amsterdam, and there was a hired car to meet, but there was one more unfortunate happeningbefore I reached my flat．In all my travels I have never, but for that once, been required by theBritish customs to open a single bag or to do more than state that I carried no goods liable to duty．Itwas, of course, my fault; the extreme tiredness and nervous tension of the journey had destroyed mydiplomacy．I was, for whichever reason, so tired that I could hardly stand, and to the question,"have you read this?" I replied with extreme foolishness,"Yes, hundreds of times．"
"And you have nothing to declare?"
"Nothing．"
"How long have you been out of this country?"
"About three months．"
"And during that time you have acquired nothing?"
"Nothing but what is on the list I have given you．"
He seemed momentarily at a loss, but then he attacked．The attack, when it came, was utterlyunexpected．
"Where did you get that watch?"
I could have kicked myself．Two days ago, when playing water games with a friend in thebath, I had forgotten to take off my ROLEX OYSTER, and it had, not unnaturally, stopped．I hadgone into the market and bought, for twelve shillings and six pence, an ugly time piece that made astrange noise．It had stopped twice, without any reason, during the journey．
I explained, but I had already lost face．I produced my own watch from a pocket, and addedthat I should be grateful if he would confiscate the replacement．
"It is not a question of confiscation," he said, "there is a fine for failing to declare dutiablegoods．And now may I please examine that Rolex?"
It took another quarter of an hour to persuade him that the Rolex was not contraband; then hebegan to search my luggage．
When did the writer arrive at London airport? A．In the early morning．
B．Late at night．
C．At noon．
D．Late in the morning．
