What a gross generalisation MayBee70, our pub will have approx 70% of customers with one vaccination and at a guess 30% -45% with two. You sanitise, walk in, sign in, with a mask on, sit at a table, place your order, table service, if your bum leaves your seat, mask is on. Tables limited to 6, no table hopping, no standing, if you break the rules you’re out. Safer than a supermarket. I object to your statement, have you been to a pub in the last year?
Unless the pub has excellent ventilation it won't be safer than a supermarket at all. The prime cause of infection is by breathing in aerosols, which can linger in the air for a long time if ventilation is poor. You could be sitting for a long period in an aerosol 'cloud' , in danger of infection every time you drop your mask to drink or eat. Distancing makes little difference in those circumstances and there is nothing magical about being restricted to 6 at a table. Being vaccinated doesn't reliably prevent infection, just makes it less severe.
Supermarkets much safer as you don't linger in those aerosols and you don't remove your mask. They're probably better ventilated, too.
It's of course down to individual choice whether or not one sits inside a pub or restaurant, but it has its risks.
Understanding of the significance of aerosols and how they behave has been very slow to sink in. Which has meant that their importance has not been properly recognised and advice properly targeted until quite recently.
