I was in Glasgow on Monday night. Out in Finnieston/Kelvingrove, through Glasgow Central and got the last train home from Central at ten to midnight.
If anything, Finnieston/Kelvingrove was whiter than it was when I was a student living there in the 90s. The strong Asian (India/Pakistan/Bangladesh etc.) presence in the businesses is now almost non-existent.
Didn't see any bother and it didn't seem dangerous.
