A man claims that a severe allergic reaction to floor polish led him to shoot a love rival.

Marco Batelli was less than happy when he saw another man taking an interest in a woman he liked and he had a drunken argument with them before going home and changing his clothes. Some time later he went to the home of his rival and shot him three times in the leg. Maybe polish affects your aim as well.

In Batelli's defense, his lawyer claimed that his client's life had started to spiral out of control following his work as a floor layer in 1994 when he developed a severe allergic reaction to the chemicals he used. I think the clue was the drunken argument.
