How would you feel if your local DIY store refused to give you a refund for a faulty can of foam? Would you get angry, or could you walk away? The Daily Telegraph reports that customer Paul Waterland (45) exorcised his anger, by spraying the faulty foam can in the store.

Clearly out of control, he then assulted the store manager Mr Knowles and a female Police Officer. The final cost to Mr Waterland ........ 200 hours of unpaid community work and a supervison order.

What was the trigger for the angry episode? The customer's sense of unfairness, his need to be respected, his need to be heard? The cause for this angry episode may have started days earlier with something totally unrelated, the can of foam was simply the final straw that broke the camels back.

How does Mr Waterland feel now? I can only imagine he wishes he had just purchased another can, so much cheaper than the final price of his anger. Remember anger doesn't go away, eventually it will explode if you don't deal with it. SORT IT before it's too late.
