My first engineering job was just a few blocks from Wall Street in lower Manhattan. At lunch, we used to walk up to Wall Street. Not to admire the financial institutions, but to get lunch. With all the money on Wall Street they had better lunch places nearby where you could get in and out quickly. In those days, engineers were only given 30 minutes for lunch.
You always could tell the Wall Street people from us young engineers. They seemed to run around with their heads cut off, eating quickly and getting back to the trading floor. As one friend who traded on the floor explained, “If you are gone for a minute, you could miss a big deal. You could lose $10,000.”
