As a related story I had a discussion with a guy that worked as head of security for a big watch manufacturing company in Switzerland (think about handmade watches worth several $10k-$100k)
He spotted some of the watchmakers casually going back home with watches in their pocket without any documentation about it, saying that they wanted to do some of the work at home. He stopped that of course.
He quickly got a call from HR explaining to him that a talented watchmaker is almost impossible to replace, they can go knock next door to another manufacturer and be hired at whatever salary they ask for. On the other hand It’s much easier to find a replacement for a head of security.
So I imagine a talented wizard would be like the watchmakers, the lab could be highly secured but with blatant security breach because the wizard cannot be bothered.
I think it’s more that the doctor was struggling to insert it, so he offer the local anesthetic only to make his job easier.
