In pubs mostly yes, unless you're just in for one beer and back out.

And when you're waiting to meet people it's mostly outside somewhere, with outerwear on, and first you walk a while to choose which pub you're going to, or to which restaurant, and maybe you'll end up sitting outside on a terrace when it's not cold enough to get inside, and you're comfortable in your jacket.
And sportswear in a pub is not bad, but it depends on the context, if all the others are there in neat office suits....

It all depends on the situation.
Weatherproof sportswear is fine on the bike to go to work, ... and casual trendy clothes are nice to go out with, but not the other way around. That's my experience.
Maybe you like to end up on an unexpected afterwork party where all your cowokers are dressed in classy blazers and you come in with a fluo North Face jacket.

I mostly don't care that much, but sometimes I think: my appearance could be better here...
