If you're talking about the risk of getting the virus myself - well that's up to me. I'm free to accept or avoid risk as I choose. If I could sign a form to opt out of NHS help should I get covid-19, I'd do so in a heartbeat.
If you're talking about the risk of transmitting it to someone else, I'd say all of the other people in the pub had accepted that risk. They were there because they'd decided that their desire for social intraction was greater than their concern over the virus. They were, so to speak, consenting adults. Of course, we were as careful as we wanted to be (no kissing, touching elbows etc...).
