Depends on how many people are in the garden and how the interact i suppose, and that's the problem, isn't it? And it's going to end up in the house, especially this time of year. As for the pubs, that's a matter for the landlord i suppose. They must have rules on social distancing and capacity, if they're not prepared to carry them out then that's not the governments fault. By that reckoning shops would have to close as it's impossible to completely social distance when overtaking the dickhead family who like to fill the aisle with their super sized backsides.
