//Maybe youve never been in a pub especially at the end of the night on friday/saturday and seen how people lose there inhibitions and forget social distancing as they sing, shout and hug (and more) others//
You're frequenting the wrong places, bobbin. The vast majority of pubs are nothing like that and I've never seen a restaurant (which are subject to the same restrictions) where anybody behaves like that. Many hospitality outlets make 25% to 30% of their annual profits in December. This government (and I'm a Tory supporter so it hurts me to say this) is presiding over the systematic destruction of an enormously important industry. It is doing so without there being any evidence that these places are any more responsible than anywhere else for the spread of infections.
