In a moment of personal crisis, how much help can you expect from a New York taxi driver? I began studying this question and found the answers interesting. One morning I got into three different taxis and announced, “Well, it’s my first day back in New York in seven years. I’ve been prison.” Not a single driver replied, so I tried again. “Yeah, I shot a man in Reno.” I explained, hoping the driver would ask me why, but nobody asked. The only response came from a Ghananian driver, “Reno? That is in Nevada?” Taxi drivers were uniformly(一致地) sympathetic when I said I’d just been fired. “This is America,” a Haitian driver said. “One door is closed. Another is open.” He argued against my plan to burn down my boss’s house: “If you do something silly and they put you away, you cannot look for another job.” A Pakistani driver even turned down a chance to profit from my loss of hope: He refused to take me to the middle of the George Washington Bridge, a $20 trip. “Why you want to go there? Go home and relax. Don’t worry. Take a new job.”One very hot weekday in July, while wearing a red skin mask and holding a stuffed(塞满的) pillowcase with the word “BANK” on it, I tried hailing(招呼) a taxi five times outside different banks. The driver picked me up every time. My ride with Guy Caaude Thevenain, a Haitian driver, was typical of the superb(一流的) assistance I received.“Is anyone following us?"“No,” said the driver, looking in his rearview mirror at traffic and me.“Let’s go across the park,” I said. “I just robbed the bank there. I got $ 25,000."“$25,000?” he asked.“Yeah, you think it was wrong to take it?”“No, man. I work 8 hours and I earn just $70. If I can do that, I do it too.”As we approached 86, Lexington Street, I pointed to the Chemical Bank.“Hey, there’s another bank,” I said, “Could you wait here a minute while I go inside?”“No, I can’t wait. Pay me now.” His reluctance may have something to do with money -- taxi drivers think the rate for waiting time is too low, but I think he wanted me to learn that even a bank robber can’t expect unconditional support.From the Ghanaian driver’s response, we can infer that ________.
