A few years ago I worked for a fancy high end cosmetic company that does all it's training in London. They get you there by train and put you up in a nice hotel with the other people on the course for the duration (four days)
I had travelled on a packed train to Euston for two hours, standing room only. I felt a bit queasy on arrival, put it down to travel sickness.
Checked in the room with my roomie - never met her before - she was 21 and I was 45 at this time so I felt a bit sorry for her that she had to share with an 'oldie' anyway we all went down to eat the buffet meal laid on.
Came back to the room and got ready for bed.. At this point I realised I had forgotten my pyjamas. Roomie lends me a t shirt (very kind) her a size 12, me a size 16 - it was like a sausage skin on me.
So I'm in bed in my knickers and this t-shirt and I start to sweat and shiver profusely. And I realise I'm going to be sick - run to the bathroom and as soon as I start being sick, I start with diarrhea, novovirus picked this moment.
So, I'm in the room with this stranger, vomiting, pooing, farting and splattering the bathroom from both ends.
Not only was the bathroom far from sound proof, but like lots of fancy hotels, the bathroom door was frosted GLASS. So essentially see through.
Spent the whole night vomiting and squirting poo and laying on the cold bathroom floor trying to cool down in between with room mate tentatively whispering "are you...Ok?" periodically.
When roomie went down for breakfast I scarpered, never to be seen again.
