Glasgow CTR is Surface to 6000ft and above that (to FL 195) is the Scottish TMA- also Class D. I do not think I have ever asked for or needed a clearance into the Scottish TMA but perhaps I should now give it a try! A bit excessive on the way from Strathaven to Bute but maybe worth a try to/from Oban or Glenforsa. Would need to climb to the south of Strathaven though to avoid the Glasgow CTA to the north (3500-6000ft).
I am not being entirely serious about this but, despite the fact that I have almost always found Glasgow controllers very helpful (and not asked for a clearance if they are clearly very busy), the management need to be reminded that the ATSU is there to provide a service to all pilots. And as was suggested by JOE-FBS, it is not their airspace but a public asset.
