Sometimes, just sometimes, it doesn’t pay to be the good Samaritan.

There you are, behind the levers of your excavator, minding your own business, when one of your comrades falls. Like the good Marine that you are, you know that no man gets left behind so you leap to the rescue.

You gently – oh so gently – lift your stricken colleague back to his feet (well, wheels) only to see all your good intentions destroyed in an instant.
