would you go to a pub where smartphones can't connect?

Yeah. I actually haven't totally figured out the apps and internet on my phone, that's how little I use it for occasions like this.
I did go to a pub alone once though and took a magazine, noone gave me any attitude.😁

Isn't interacting with the other patrons the whole point of going to a pub?

Yes, I rarely use my phone when I go out.

I stopped reading after "would you go to a pub".
Yes

sure, assuming they're not serving shitty low calorie watered down craft beer that tastes like beer flavored water and costs $5 per 8oz glass (like most of the "pubs" around here)... 🤔

If I was in company then "yes", probably. If I was alone - and I don't go drinking by myself very often nowadays - probably "no"

Unless I’m alone. I try to never take it out.

Mine normally stays in the truck

Absolutely!
