Spur Birchwood = Sickness

On April 3rd 2017 i went with 2 friends with birchwood spur in Boksburg. The next day both were sick and blamed it on the spur. I thought nothing of it. Yesterday a friend of mine returned from the Free State. I decided to take him for dinner and we my girlfriend. Friend and myself each ordered a bacon and cheese burger. Our son ordered the macarony. This morning all 3 of us awoke and are very sick our child is 100%. I phoned the manager "Brett" and told him about this incident. I told him i dont want anything i dont expect him to pay for doctors fee. I just think it is ridiculous that this is the second time at this specific spur where there has been this sort of incident. Brett claims he doubts its from them. Last time i eat at this spur. Discrace to the spur name
