I've spent a great deal of time in Scotland and the beer's just as cold as it is here. You can even purchase draft Guinness at pubs advertised as 'extra cold'.

I've never seen soft drinks served any way but well chilled - even says so on Pepsi bottles. Otherwise, a glass with ice accompanies your soft drink.

This is as recent as last month.

Draft Guinness served in the US is brewed in Ireland, though it can suffer a bit during the physical transport across the Atlantic and subsequent distribution. Guinness served in cans & bottles for American consumption is brewed in Canada.

And Budweiser & Miller are popular in Scotland as well, though cannot understand why.
