In the US they are usually baristas.Not much to add, the video covers it pretty well.
I've seen some funeral processions and services with strippers and pole dancers before, but they were much more common in my youth (in the 80s and 90s) compared to the modern day. I honestly couldn't tell you why there are funeral strippers though. Is it meant to draw more people to your funeral? Possibly. Is it a way to send off the deceased in glamor and glitz? Maybe. Is it just an excuse to see some strippers and pole dancers? Also possible.
Funnily enough, though, funerals are not the only places you'd see strippers. I've also seen strippers pop up at religious festivals, political rallies, weddings, outdoor concerts, etc. Again, much more common when I was a kid, much less common these days.
Also, Taiwan is home to betel nut beauties. They're less common these days after the government started cracking down on them, but for a while they were a really unique and beautiful part of Taiwanese culture.
I guess the Taiwanese just really like strippers.
