Have everyone sign wavers at the door? I mean no one is entitled to go, nor does the venue have to let anyone in.
Then I suppose you could go down the route of: What if someone got sick at the event and then outside of the event they are shopping at Kroger and get someone there sick and that person finds out the other person was at a big event and tries to sue? I suppose then you would have to prove they got it at the event which I assume would be really hard to prove.
Idk just throwing stuff out there.
