If a person is healthy and feels fine there is no reason for them to not do what they want to do within reason. Going out to eat or for a drink is not a mortal sin, not now, not ever. It's their choice and they shouldn't be cast as villans. If somebody wants to stay in their bedroom for the next 2 weeks that is their choice also.
It's been said over and over that you can be symptom-free and have the virus. People can show some self-control and not go out for a drink for a little. It's not that hard.
