Employees fighting with blood on my groceries

Saturday 4 July 2015 +-10h30 myself and my 6yr old son went to do our monthly Grocery shopping at Giant Hyper. Upon walking inside close to the cleaning materials section a seem to be Manager was verbally fighting with a seem to be worker, something about lunch and going over his time but very angry and swearing words coming from the manager. This already is unacceptable and creates a negative feeling. Once done we went to the till to pay, we were at a till close to the exit door and a small office on the right. I had 2 trolleys at end of the till point.Suddenly we hear a commotion,several staff ran to this small office on the right of the exit door. I asked the till operator,she also went to check, came back looking startled and told me its 2 people fighting, both employees of Giant. They were physically hitting each other, they started running out into the shop and ran over my trolley it landed meters away, the men covered in blood, the ones eye badly bleeding,almost ran over a small child, everyone in shock and fear. They replaced a few of my bags as it had blood on. At home I found more blood on my food packets. Infectious diseases? Maybe public should know before going again.
