I agree, Rolf. That one's a bit funny, but it's a valid concern. And let's not forget the low-probability but high-impact issues. Gotta be ready for anything with a machine this complex.

Ah, option D made me chuckle. A small child trying to steam milk? Now that's a mental image I didn't need. But hey, gotta cover all the bases, right?

I'm with you on that, Leatha. But I'm also a bit worried about option C. Untrained customers trying to use the machine? Recipe for disaster, if you ask me.

We definitely need to make sure the instructions are clear and easy to follow.

Hmm, I'd say option B is the biggest concern here. If the instructions are wrong or out of order, that could lead to some serious issues with the machine. Gotta get those step-by-step instructions spot on.
