I remember seeing a video of a rubber arm experiment that goes through a series of exercises to convince someone’s mind that a rubber arm placed against their shoulder is theirs, while the real one is blocked out of sight. Once these phantom sensations are in place, the organizer then hits the rubber hand with a hammer, causing great shock in the subject but no real harm. The immediate panic is exaggerated by the fact their mind can’t actually move “their” hand out of the way when they see the swing coming.

Another study had organizers shine a harmless light on participants’ arm for a few minutes and see how they react, allegedly for some sampling purpose. The twist was that they would have the real subjects stay in a waiting room beforehand and watch actors leave while appearing to be in considerable pain from the session where the light was targeting. They then experienced a significant burning sensation from the “laser” despite the organizers insisting it was harmless. Some would go as far as to raise their voice and demand the experiment stop.

The idea is that people can be convinced that something is painful just from others’ reactions to it. This may have been what the organizers were actually testing for, and the electrical shock wasn’t real or was barely large enough to felt. But OP was just immune to being influenced. I would expect the ability to follow cues from others has strong correlation to success at socializing, so considering they use 4chan OP might actually just be built different.

The jokers are very specifically worded for things like this. Usually they will say they give a bonus if a hand contains a certain (scoring) pattern. A straight flush contains both a straight and a flush, so jokers specifying one such contain trigger will proc. Similarly a full house contains a pair, two pair, and three of a kind too.

Rarely, jokers will specify you must play a hand instead, which means it must exactly match what is listed as the scoring pattern (except I think royal flush is still a straight flush), similar to planet upgrades. To do list is one example, because otherwise something like a three of a kind roll would be strictly worse than a pair.

Two pair seems to require two different pairs in a scoring hand to proc, meaning it doesn’t count four or five of a kind hands. Some people disagree with this ruling.

This style of activism is harmful to the cause. No one in that restaurant is going to think “Huh, those people had a point. I will consider their message more.” They’ll simply resolve that vegans are crazy and annoying, and be pushed further than ever from converting. Honestly shouting like this is just performative for the people doing it. The best ways to be an activist imo are engaging people personally (like Earthling Ed’s good-faith debates) or even just presenting people with information and going for numbers, relying on people engaging in self-reflection on their own.
