No way!!
That's going to be a real delight in the summer!
I think it'll cause more problems than it solves.
My personal issue with eating/drinking out is people handling the food, cup,plate etc and coughing/breathing/sneezing on the food.
Much more than someone sitting 2m away outside (which is the first style of 'eating out' I will consider).
Obviously,as he says,it'll be difficult/impossible to survive with far fewer tables - but there's still takeaway options and people will have to accept paying more 🤷🏻♀️
But, no, coffee in a hot sticky enclosed space that looks like a Morgue- doesn't appeal, funnily enough!
