That looks like what you also see at any typical campground in the US. To refer to their work as a "Handyman special" would actually be a compliment.
I've always wondered how this stuff goes on, I mean there must be fire marshals or electrical inspectors who visit these places even as regular citizens. Even in their off-time, you would think that they would follow up when they got back to work. I understand that inspectors don't have the same enforcement authority as police officers, but come on. Even a novice can tell that this stuff is a major hazard.
Thank goodness that they don't sell rocket propellant at home centers. YET.
