Bus drivers refused to stop their buses for foreign workers. Commuters squeezed their noses when foreign workers approached and gave them a disgusting look. What more? Human beans are human beans. Not many are saints. The little irritation in life can become a big issue to some. Some have higher tolerance level, some are more kind, some more forgiving and some more friendly. But some are more nasty and have very low tolerance. And this will apply to both sides of the equation. Bus drivers can drive off. But they may end up as the punching bag of angry foreign workers. People may squeeze their noses or walk away. One day they may get slap and punch by angry foreign workers as well for being rude. Then what?
