Food poisoning

I went to Maponya mall on Saturday 29/07/2023 evening with my husband and kids. We went to steers to buy 2 ice-creams and a cheesy bacon burger. I placed an order while my husband was watching the kids and asked him to come make the payment while I watch the kids. When he was about to make the payment the lady who was serving us wanted to include a full chicken and said that we ordered one telling the people in the kitchen. I don't know if she did that because she saw he was a bit tipsy but he told her off because we never made an order for a chicken. On Sunday when I woke up I had bad stomach cramps which later led to a bad fever, headache and body pains. I went to the Dr on Monday and he confirmed that it was food poisoning. It made sense to me that I was the only one who ate that burger while everyone else in the house ate the same thing and I woke up sick while everyone else was okay. I've been sick since Sunday it is only today I feel better, not fully recovered but I am better.
