I have an event at the weekend we all have tickets. My friend got covid last week and has a bad cold and cough and still testing positive. I realise guidelines have changed but I told my friend that if she's still testing positive the day of event I'm not prepared to car share and go with her. She's took a hissy fit. I said it's unfair to spread it. I don't think I'm being unreasonable. You cant board a plane , go on a cruise etc. Am I being unreasonable? I have not been near her and don't want to catch it and its unfair if others catch it.
