     In a moment of personal crisis, how much help can you expect from a Ne 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 in 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 Ghanaian

driver, "Reno? That is in Nevada?"

     Taxi drivers were uniformly 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. A

Pakistani driver even turned down a chance to profit from my loss of hope; he refused to take me to the middle

of 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 ski mask and holding a stuffed pillowcase with the word

"BANK" on it, I tried calling a taxi five times outside different banks. The driver picked me up every time. My

ride with a Haitian driver was typical of the superb assistance I received.

     "Let's go across the park." I said. "I just robbed the bank there. I got $ 25 000."

     "$ 25 0007" He asked.

     "Yeah, you think it was wrong to take it?"

     "No, man. I work 8 hours and I don't make almost $ 70. If I can do that, I do it too."

     As we approached 86th and Lexington, 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.
