Unspoken social rules in Scotland?

Hello! I’m in my mid-30’s moving to Glasgow for one year for a postgraduate program. I’ve been to Scotland on 4 or 5 visits but A) never for more than a couple of weeks at a time, and B) I’ve not spent much time in Glasgow specifically. At the risk of getting roasted for asking this, I’m curious — are there any unspoken social rules/public etiquette/household practices you can think of that apply to Scotland specifically?

Not looking to avoid learning most things the hard way, mostly just curious!
