I think that tie is of no use though I always have it on while working.
One midnight I missed the last train and I was at a loss. But soon one
cab came to me and took me home. Then the driver said, "if you didn't
wear a tie, I wouldn't take you up. The (drunken) men in working clothes
are so rude." Certainly whom to take up late night may be fatal for
taxi drivers. Tie is one of the things that seem of no use in modern
society, but as long as many people judge by appearance it should be a
necessary item for men to do good business.
