On holiday in a rented cottage and as we were there for 2 weeks we had the sheets changed in the middle. All good and fine. Until a few days later the owner approaches me with the washed sheets and asks me what I think the STAINS on one of them might be????? 
She says she wants to know so that she can know which stain remover to use!!!

They were small blobs of browny red and were obviously blood. 
Arrrgh !!!
I just muttered ignorance and wished the floor would open up and swallow me up.
She definitely knew what it was and knew it was me and I think wanted to charge me. And we still haven't had the deposit back so who knows, maybe she still will.
Is she BU for showing a guest stained sheets or am I for being so upset about it???
Please please also tell me some holiday horror stories of your own so i can ( hopefully) realise im not on my own!
