If all of this is based on the r rate which can drop daily

Why has Boris just put tens of thousands out of work by picking a random date in the future and telling an entire industry that it must close until a completely random date significantly in the future?

I guarantee that many many people will be handed their notice now because he's just told their bosses that they are not allowed to operate for months and for what? The r rate could drop dramatically in the coming days. Those industries could adopt the same social distancing measures that others are allowed to do. But nope, jobs gone due to a stupid statement.

Which has more risk of spreading covid-19? A cafe who can take away half of its tables to ensure they are all several metres apart, move some of its tables outside, place disposable covers over its seats and tables and has a relatively low turnover of people
Or Tesco who has no way at all of controlling how close it's customers are once indoors, who has trolleys and baskets touched by hundred of people daily, who has no way of stopping people from picking up and putting down the products, who can't stop people from holding a tshirt up to them to see what they think etc?

 

If the R rate stays below 1 Pirates are f@cked
