Adding to that, you could easily kill potentially dozens of people unintentionally by serving bad food from just one shift. It might be considered intentionally neglectful, but that can be arguedAnd what is the problem with that?
That one form they fill out checks your criminal history, if you've had any mental issues or domestic violence charges and if you have charges pending.
Also what the people are buying are not "assault" rifles.
What more would you propose?
You can't unintentionally kill dozens of people with a rifle. However, Im not against requiring a mental health check prior to purchase and/or having to re-up on it every 6-12 months just for the safety of the general public. And social media posts should be included in background checks, which would make the process a couple days longer than instant clearance
