No amount of rationalising will deflect from the fact that the rules are confusing and open to exploitation. While some of us follow the rules others flaunt them. It is because of this that the lockdowns have been extended and may be for longer still. N
None of those rules should be exploited through misunderstanding, they could only really be exploited intentionally, by the vendors, albeit not for long in public settings.
As for the punters, the rules are only confusing to the easily confused, thankfully most understand the rules.
The logical mathematical reasoning for the rules is more complex, most will get the basics of it, but loads don't and most people have zero idea how to evaluate risk.
Not sure what you mean by ramming a pharmacy with at risk people when there were 4 of us? all fully vaccinated and all wearing masks. Maybe you didn't read that bit?
I did read it, but you and the three other guys outside don't know how to evaluate risk, it seems. Albeit one may have, and just agreed with you to avoid having to explain the logic, as it is a bit longwinded.
I'll explain here though:
Don't think of it like just you 4, that were outside, your instance isn't every instance, it could have been 10 and they could have been all inside, unvaccinated with your theory, and it could have been like that all day. You have to account for all times and all places, especially in places which would see a lot of people "at increased risk".
A busy pharmacy probably gets >1,000 customers per day. 1000 people inside, looking and queuing, at the same time as say 3-10 others, for 5-20 minutes, or inside, on their own for 1-2 minutes? The time/ exposure risk is probably ~10% by being outside.
The mask/ vaccine is irrelevant, even if this reduces your risk by 80% (example). There's still 20% of "risk" left, and by being indoors you may still have say 100% of that 20% risk, yet by all being outside you're 10% of 20% risk, as your exposure is 10%, so your risk is now 2%, rather than 20%.
If the others were unvaccinated and old, they may be at 90% risk (example), and you seem to want them to stay at 90% and stand inside and queue with you, when they could be at 9% outside, ery easily, with zero hardship.
Or do we need someone stood outside asking everyone for their vaccine status, calculating when they had their second dose, how many are in the shop, what is the estimated time to service, then do a full risk assessment for each patient that enters? No, because that's stupid, just wait outside, it's not an issue.
