Most electricians know when they are dealing with danger when it comes to working on some wiring. Most.
This restaurant apparently hired an electrician from Wish.com to do some work above the salad bar and it seems like they got what they paid for.
This dude cuts into a live wire and immediately regrets it. Dude suddenly is showered in so many sparks Goldberg would give him his seal of approval. You can even see that he's wincing as he starts to cut into the wire, even knowing that he is dipping his toes in danger.
Dude gets knocked off his ladder but no one seems to react so I guess he's okay, besides having his eyebrows singed off.
