this is a controversial opinion: auto-menders aren't very good

[DJ-Fireball_did_this]

What if auto-menders took longer for non-doctors? Like you know that little progress bar from using it? Maybe the time could be changes depending on the person's actual job. In-universe it's because they have medical training and using one is a great deal more complex than it may seem, out-of-universe it's so there's an actual function to medbay and the people inside it.
