This was the closest CML lab open on a Saturday.
The wait time was longer than average, taking about 45 mins from when I walked in the door.
There are a couple confidentiality concerns. The reception desk is configured in such a way that everyone within the waiting room can hear everything being said. This included staff talking about non-work related issues.
While I was personally treated professionally, a bit concerning was how rudely the staff spoke to clients who were newcomers/who spoke English as a second language. They were unwilling to make any extra effort in helping them navigate the services they needed.
