Cooking blind
Some people may not see any flaws in a design, while others may find it inconvenient. When other folks use this extractor, it’s probably never really occurred to them that it might be an issue, but this guy is genuinely having a hard time seeing his dinner.
On the other hand, if he wanted to pull up a chair and cook while sitting down, that would be an option. Sure, it’s bound to be uncomfortable and potentially hazardous… Okay, that was a poor choice. On another note, it appears as though he’s doing a decent job – even if he isn’t looking at it.
