What is the worst thing that has happened to you while travelling/while on vacation?

The worse the better (for getting 10 points)lol
But no fabricated stories...only the real deal.

nah!!!! the worst is not so bad. The aircraft have delay for 6 hours!!!!!!
also I got fever during my trip to China, luckily it recover after 1 day.

i got infected eczema .. had a big patch of bloody scabby mess on my arm.. not nice!

delayed for a week in bermuda. as fault with aircraft then we were forced to land at a place called santa maria and were there for just under 24 hrs.

I had a tooth extracted a couple of days before a transAtlantic flight and was on antibiotics. I was traveling alone, and the medicine made me airsick. Nothing worse than being alone at night with people who don't speak your language, and sick to your stomach. BTW, that was the only time I ever got airsick.
