This is oh sweet summer child stuff.

Have you ever gone to a crowded public place and setup an open hotspot?

Ah I think I never had to do connect to a public open hotspot because by the time I grew up 4G and then 5G internet were commonplace.

Never travelled to another country and needed internet before you could get a local sim working?

Airport is prime for this but in general the average person keeps wifi on and the click through on an Android to use open networks is so seamless

esim for the win.

And you have them in your laptop? Or just using your phone and don't own a laptop at all?

I would use my phone's 'hotspot' long before I tried random wifi on my laptop?

Are you being willfully obtuse or do you actually believe that's true of everyone? There are so many reasons why someone might have a laptop in such a situation but not be able to use a hotspot on their phone - it's not even worth listing them.

That isn't what this thread suggested; I was supporting plausibility of the GP's claim never to have used public Wifi because of good 4G; stating they could still have used a laptop in public. My wording was also explicit that this isn't always an option.
