I have gone out with a mate or mates and stood out with them when they fancy a smoke, more often though I don't. Most of my mates that do smoke, if we are outside with non-smokers will refrain from smoking at the table out of courtesy. Or will go to a further bit or out to the front if they want to. It is the others around that still make it shit.
I've never heard of vaping being separated from smoking tbf, the ban covers both.
I disagree on smoke from beer gardens, but it can vary depending on a lot of things, size, number etc. There are many people that actively avoid being outside because of it, I have moved inside on many occasions both with family and with smoking friends who get that. I would welcome a ban on beer gardens. Or on the whole thing altgether tbf.
