Hotels using sheets instead of duvet covers?

[WeepingBicycleMonkeys]

Lighthearted, first world problems before the po faced appear but for the love of God, is it really really so much more time consuming to quickly slip a duvet cover on?
All that elaborate folding of the two sheets to cover the bare duvet must surely take more time?
Longer than even the most inept duvet cover-er would take.

We are currently in an American chain hotel and I'm becoming mildly irritated by the nightly battle to keep my sleeping drooling face away from said naked quilt.
It makes it impossible to just have the top sheet over me when DH favours the full compliment of bed covers as it involves unravelling complex folding mechanism.

Anyone work in a hotel that can shed some light? AIBU? and, do the duvets themselves ever get washed?
Actually, maybe don't answer that bit for another few days

Here in NZ they do use duvets most of the time but always have a top sheet too. I think that they change the top sheet and not the duvet cover - that is certainly the case with friends. Because I worry that they might think us mingers, I have had to explain to friends who stay over that we don't have top sheets (except flannel ones in winter) but that we wash the duvet cover every time (and that I have a second plain white cover beneath the pretty top one, to save the duvet from dribbles).

I used to be a chambermaid in various hotels. All had starchy sheets fresh each time and then big eiderdown covers and we folded the pillows into the top of the eiderdown just for show. The covers never got washed and I always used to think how many people had had sex on top of them or eaten snacks watching TV.

The duvet between two sheets things sounds irritating.
