"I was perturbed at the length of queue"

I attended St Andrews Community for my second Covid vaccination. I was perturbed at the length of queue which required a large number of people to wait in unventilated corridors. There was no signage to let people know they had to check in. When someone eventually informed me of this, I then had to walk against a one-way system to get back to the queue where I had lost my place as several more people were now in front of me. I cannot understand why so many people would be given appointments at the same time when there is not a safe way of managing the numbers. At a time when Covid levels are increasing in this area, it is a worry that a vaccination centre could be a Covid spreading centre.
