What is the appeal of these Karen Diners?

I've been twice and it's pretty much just for a laugh really. It does get old quickly though and I don't plan on going back. The first time I went was with a friend before a concert. We saw it in town after both seeing it on tiktok and since we were looking for somewhere to grab lunch, we went in. That time it was so busy that we didn't get much of the experience focussed on us. It was still hilarious getting to watch other people get grilled and forced to stand up to be publicly humiliated. The food was good though, amazing chicken wings. We found it funny though a bit shocking too because it just feels so wrong to be sworn at and hurled abuse by restaurant staff but it was pretty fun. The second time we went was on my younger brother's birthday as he wanted to go and that was a much more fun experience as the restaurant was empty except for three groups of people (we went during school and work times for early lunch) and since it was my brother's birthday, he got a lot of the focus on him. This time we all participated and actually got involved in the conversations with staff more instead of just sitting there shocked and laughing like the time me and my friend went, now that was fun. We got called up to play different games and made to do ridiculous things such as catwalks to wildly inappropriate songs, animal impressions and karaoke. The staff were good at their job too, getting other tables involved with eachother and even practically dragging my brother along to do the games (he got embarrassed and just stood there like a melon). Even the chef started getting involved the second time I went. We also all enjoyed the food and their milkshakes are actually really good. But overall it's one of those things where it does get old fast and I'd rather not go back again any time too soon because the novelty has worn off. Maybe I'd go back with some different people to see their reactions but honestly I'm bored of it now. It's also not very cheap since you're paying for the extra service in the price of the food so it's definitely a once or twice kind of thing. The food was nice, the experience was interesting and fun to try out and they're good at getting everyone involved but you have to have a certain sense of humour and thick skin to manage it because they can and will be brutal sometimes.
