Do what I do and lie.
I was asked the other day by one of my colleagues, a fanatical Branch Covidian, whether I had gotten the jab. Of course I have, the Pfizer, which we both agreed was the best one,. Mutual congrats all round and he left happy. He's a fat, retarded troublemaker and I give zero fucks about misleading any rude fuck who'd ask.
Besides the Covid passports are not going to work. Unless they bring in a Chinese style top down surveillance state people are too lazy to comply. Remember the contact tracing apps that were supposed to track down all the potential coof cases? Total waste of time. The idea that every shop, gym, sports stadium and bowling alley in the country is going to ask you to show your papers as a condition of service is hilariously unrealistic. Besides I imagine it will be trivially easy to cheat the system. I 'm from a country where millions of illegals drive, work, go to school and vote with no paperwork. Our government is too lazy and incompetent to run a system like that, their ambitions way outmatch their abilities.
