just to confirm, (as AmperZand wasn't sure), Glasgow shop has Pick a Minifig stand. The only time I've been (2 months ago roughly), it seemed to have a few Halloween type things - my kids picked a couple of witches hats and skeleton heads. There was also a neat wee soldier's hat, which I had never seen in any sets.
I don't think Pick a Model was there - there was a blank strip of empty holes, which I've read on other threads can indicate an out of stock pick a model. But, as I said, only time I've been there, so not sure how they are usually setup.
