Staples in my food, shocked!

<p>I am a regular shopper at Woolies and really enjoy their quality food. Yesterday however I prepared their Beef Burger Patties and while eating them I heard a crack noise in my mouth. I came to the shock conclusion that one of the patties had a staple in them and now I am sitting with a chipped tooth.</p> <p>Woolworths SA , please make sure this does not happen again. Really disappointed.</p>
