Ok not all staff but some I met today.
Had appointment to get Dds passports today at 11am. I arrive early at 10.30am to no queue but told I'm not allowed to queue until 10.50am and to come back then. We come back at 10.50 to nice long queue which takes 30 to get though.
While standing waiting another family arrive with a teenager who clearly had disabilities but they are turned away for being too early as well. They ask of their son can use the disabled loo, and told no because they aren't allowed to queue and go though security checks. The guard could have easily let them in barrier, and then seen them into loo and out again without them causing any trouble, or any risk of harm. They are told to go elsewh
After we get to waiting area there is again no queue but again 10 mins before appointments, massive queue.
I felt very bad for the family who couldn't let their son use loo.
As for being set away, there is nowhere else in the building to sit.
Maybe I'm just grumpy after a long wait with my own two SN kids who aren't great at queues and waiting and crowded places, only to be told I didn't have to bring them with me as the lady on the phone told menu had to.
