You say a dozen having a house party why not say 60 in a small house with no covid 19 controls and as the drink will be 50p a bottle instead of £4 thus they will drink a lot more than normal,I have not been out much recently but on Monday night went to Levante kitchen and first had a beer in the Wynnstay and Nags head,the covid 19 controls of these three establishments is very good and I felt pretty safe,I can see what you mean that on a mad friday it can get out of hand but now you will have more youngsters being in contact and spreading the covid 19 to the older generation.
