I dont know about the rest of you, but I am finding that the vaccine mandates are really just a joke when it comes to enforcement, at least in the USA.
I was in New Orleans in October for about a week for work, and they have a vaccine mandate in place for entering any restaurant. Not going to lie, even though it was a business trip, I visited quite a few local establishments and imbibed a bit more then I probably should have, but I was still in bed by 10 every night.
Only half of the places checked my for my vaccination card, and a picture of my card on my phone was more then enough, which they only glanced at it. Just one establishment insisted on actually taking the time to compare my ID with the picture of my card to ensure the names were the same.
I have been to NYC several times since their mandate went into effect, and the same thing. Recently I had a shoot at a major University in the Bronx where we needed a scissor lift. Before I arrived, I found out the driver of the truck delivering the lift was not vaccinated and he was not even allowed to drive on campus to drop it off. He had to leave it on the sidewalk and then it had to be driven into campus. (The battery was dead too, so it was kind of a funny situation daisy chaining a half dozen extension cords to plug it in.)
Initially I was worried they would be serious enough to want to see my physical vaccination card, which I did not have on me. Nope, just like everywhere else, security just glanced at my phone just long enough to see a picture of a card and let me in. That was it.
That one dive bar in New Orleans has been the only place, whether I was working on a project or just out to eat/shop, where they actually took the time to confirm it was my card with my name on it. I'm sorry, but the ease at getting around this is a joke. Likewise, I highly doubt most employers, even those whom enacted a mandate themselves, are going to any further lengths to verify the authenticity of vaccination of their employees.
Now I will be traveling to the UAE for a month on business soon, so I am expecting that their verification process will be a little more intense but we will see.
