People always take sleeping outside for too long as something that's always painful or uncomfortable. Back when I was a scout and often camped, I found it easier to sleep there than back home. Not that I find it easy to sleep normally, but it was still easier then.
Bed wars. Yeah, srs bznz.
Yeah, sometimes the best solution is to just avoid it and lock the door.
This manga takes so long to update that I forget some plot. But I still laugh when I read this. 😆.
The plot is just what he mentioned: "This is all for Japanese food." That's it.
Alfried is normally such a relaxed and easygoing person, not arrogant or overbearing, that occasionally it's perfectly reasonable for him to behave like the scion of noble family and refuse to share his room with such loud troublemakers.
I don't think you have to be as relaxed and easygoing as him to refuse those people. You just have to be better, which isn't that high of a bar (not that there aren't a lot of manga characters who'd fail that anyway, but still).
I don't know why fantasy manga always put people on top of the tarp for covered wagons. That doesn't support weight, it's to protect from the environment!
I've seen characters sitting on top of tents as well. It's not exactly a good idea.
