Booking for a pint that can only be drunk in a beer garden at an allotted time just shows how far from normal things like pubs are going to be. I will be giving all that a wide berth until it's punted and pubs are back to normal. If people flock to them with these sort of restrictions still in place I suspect it's simply going to prolong the whole circus but as you did point out you just want a pint which is if course fine.
Pubs beer gardens are best avoided for a while after they open. They'll be like the Friday before xmas with all of the part time drinkers etc.
There's inevitably going to be more cases in schools etc with the LFT's taking place. The only number that counts is deaths rate and nobody has got the balls to come out and say what's acceptable.
