So common.  Many years ago, this happened so many times to one blind guy
here in Denver, he was in his fifties at the time, he was waiting for his
regular bus one morning, and when the doors opened, he spoke to the driver,
a none too friendly fellow in the first place, and recognizing his voice,
climbed up the steps to where the driver was sitting, and said, I'm sick of
you dropping me off at the wrong place, and whipped out a mase spray.  the
cops were called and the blind guy spent the night in jail.  It was worth
it, though.
