It sounds like you're expressing a sentiment about personal responsibility regarding smoke from a campfire. People who choose to camp near a campfire should be aware of the potential risks and take responsibility for their own health and comfort. If the smoke is bothersome or affects their health, it is indeed their choice to stay or move to a different location.
It's always a good idea to communicate with fellow campers and ensure everyone is comfortable, and to consider wind direction when setting up a campfire to minimize smoke exposure to others. Is there something specific you'd like to discuss or clarify about this topic?
