It would be good if the DT Glasgow Central could sort this out.

Despite the sign outside the lounge which appeared a while back, I get the impression there are many people in there who are in excess of the guest limit, e.g. not even staying in the same room or without Diamond status.

And there's still many guests - shamelessly and without any challenge from the staff - using it as a free convenience store, walking in and grabbing handfuls of snacks and drinks (or stuffing them into their bags) and leaving immediately afterwards.
