I hate hypotheticals but here I am with one anyway. It's your wedding day and you wanted to be cautious and could spend hundreds/thousands of dollars on FDA approved saliva tests for your guests. Do you do it to make sure everyone is safe? Do you hope that everyone has been taking care of themselves because what if someone really special to you tested positive, would you tell them they couldn't be there anymore? Something I would consider for my wedding but I would be so nervous at the same time.
