OK, but the thread title is "Do you think vaccine passports should be required to get in to pubs". I answered that it should be at the landlords discretion. I really don't see why that's off topic. (I don't think it should be a legal requirement though).
If my specific response to you was off-topic, then apologies.
I don't think vaccine passports should routinely be a mandatory thing though. However, other organisations (some cruise ships) have said that customers will need proof of vaccination. Maybe from your GP perhaps(?), but some sort of optional vaccine 'passport' might become a thing. It's more certification really.
As for people on this thread who say people will just buy fake certificates. Is that not just as selfish as some of the breaking lockdown rules, which has been so heavily condemned on here?
