For people who are struggling with "but if I'm doing X this already puts me at a large amount of risk so I might as well do Y", try thinking of it as the Hunger Games.
Every social interaction gives you a certain amount of slips. School gives you 30 slips daily. Going to work in an office, 20 slips daily. Going to the pub, 20 slips. Going to a crowded football match, 50 slips. Visiting a friend outdoors, 1 slip. Visiting a friend indoors, 3 slips. Everything has a price. And no, having a slip is not a death sentence - everyone is going to need a certain amount of slips to live.
The idea is not to reduce your slips to zero, it is to keep them generally down. So, the price of sending your kid to school every day? Probably worth it. But if you are also going to the pub, inviting all your mates back to your house and so forth, then the amount of accumulated slips becomes overwhelming and sooner or later the odds are not in your favour.
(It's worth noting that I suspect the problem with pubs is on average very little to do with pubs themselves but more to do with the fact that the average person walking into a crowded pub right now is less likely to be viewing risk this way. So each one of them will have a higher than normal amount of accumulated slips, they are more likely to be carrying it in, and having carried it in are more likely to be visiting other places where they can spread it. This is unfortunate as there is absolutely nothing the pubs can do to prevent this.)
