With some management types one gets a feeling that they are always looking for a reason to close. Close correlation with clipboards, high-vis jackets and an overwhelming desire to be seen to be taking decisive action.
I am presently involved with managing a premises (as landlord) for a pub operator which has asked our advice. The line at the moment is that unless the government mandates you close, or you can't get enough staff to open because they're all ill, then stay open. Precautionary closures without real direct cause other than "due to the Covid-19 outbreak" do more harm than good and just foster a sense of the world coming to a standstill.
"How will we pay the staff"? Well, for now, with the money you're not spending on your business rates because they've been suspended for 12 months. Then go to a skeleton staff because you're not going to be busy. Then apply for one of the grants the Chancellor has made available.
