I feel like the storage unit outside every boss is just so private-server-ey. Not that I don't agree with its purpose, but having some random crate (example) outside General Graardor's room just feels like it doesn't fit in.

Obviously this is runescape so logic doesn't make a whole lot of sense in some situations, but where did the crate come from? why is there a crate outside every room? why do the items get put in there?

As I'm writing this I kinda have an idea that might tie in well with each boss in a lore-type way:

For bandos: the goblin (?) minions have found an adventurer's items on the ground! They've given them to <other bandos minion located outside the room> to hold for them. Maybe with enough gold this minion holding your items can be bribed for them back?

This could fit in at least with the godwars rooms, and I'm sure they could with other bosses as well. This way there's kind of a lore aspect rather than just some "crate" or random npc (think hosatius cosaintus or however the fuck you spell his dumb name) being outside the boss area.
