Cold beans are bad enough without people watching, derekd47 nailed that. Test your stuff before you go, every single time. I bring a tiny backup stove now, never get caught like that again.

That museum is a real humbling experience, isn't it? Seeing those perfect joints cut by hand centuries ago. The wood fits together so tight you can't even see the lines. It's like watching a master chef cook when you can barely scramble eggs. Totally get why it would make any modern shortcut feel a bit lame.
