Hi guys so I'm emet and I work in a bar, on Thursday one of my work colleagues called in sick saying she had been up all night with food poisoning. She came in on the Friday and seemed fine so I thought nothing of it but then yesterday I started feeling queasy and worried that she could have something contagious.... I know it takes 48 hours for symptoms sometimes but I just want to know if I would have more than one symptom by now?....
