To my great shock and horror... Innkeepers do not give a refund for empty wine bottles. I can barely overcome my astonishment at this completely unacceptable business behavior.

No wonder empty wine bottles are littering even the nicest dungeons. The most environmentally minded necromancer would not be able to dispose of them properly in the dark of night without having to lose all self respect by dealing with lowly and hard to find thieves guild fences. Our hapless and self-respecting necromancer would have to boldly venture into town during daylight shopping hours to return his empty bottles, or wait shuddering in the cold for the next khajiit caravan to pass by. I mean, seriously, this just will not do.

Not to mention you can't find a trashcan anywhere.

Yay for trolling!

Yeah, and all that fur in the armor....
Why they are killing poor animals?
Why they can't use jeans and like normal people do?

And why are there no toilets?

there is no plumbing, there are stools with a bucket next to them though

Why are there empty wine bottles but the mead bottles are always full.... some foul Nord magic is afoot?
