Disagree. Intentionally sitting on your hands hoping others fail is the exact opposite of what a professional should be doing. Absolute worst-case, you should be finding a way to get your concerns documented and on the record. Better would be to do what you can to make it succeed. That's a far more valuable and sought-after skill, than someone whose default position is to say "I knew it wouldn't work" or "I told you so" after the fact.

Not sure where you're based, but as a data point, in the UK 70% of businesses fail in under 10 years. Having worked at a company that no longer exists isn't -in any way- a reflection on yourself or your capabilities. I'd suggest the larger issue is being able to demonstrate a particular skillset without recent roles that use it. To that end, I'd be fairly exhaustive when listing skills you've had to use for your own businesses.

Good communication is key and you should give them every opportunity to report the failing themselves but if they won't, then reporting up is the only option.

Making a mistake is bad but forgivable. Intentionally trying to cover it up isn't a mistake, it's a considered action.

In the UK students sign waivers at Uni allowing companies to verify qualifications without a data breach. That said... We once hired a marine engineer with excellent qualifications. He was sent out to do an inspection on an LPG support ship, and we had to recall him when he submitted a plan that involved flooding the ship from the inside while in a dry dock to check for leaks. We called the issuing bodies and the qualifications were all fake.

"It's my responsibility to get drinks for the group during meetings" sounds very specific. Was that perhaps mentioned in the interview/early on? Is it possible your boss meant to say "During meetings, etc..." but said or you heard "During meetings"?

Re: Being an over-reaction... It depends on how long this has been happening. A minor annoyance on week 1 can easily become a major issue after 6 months of repeats, each one adding to the frustration. Of course, that's why it's good to address these things early [I tend to give people a few false starts before I'll comment, in case it's an outlier]

"When you can not answer a question in a job interview, then "I don't know, but I would do [x] to find out" is almost always better than dodging the question or awkward guessing". This. When someone starts uhm-ing and ah-ing, then comes up with a wrong answer, that's a red flag. Someone who says "Not a clue but I can find out"? That's far more valuable to us.

"Hold on a moment. I think there's a different way to approach this that may help"

"Raise a ticket and i'll get back to you when I have an opportunity"
