Reading the story about the unfortunate death of a holiday-maker in Northern Cyprus as a direct result of drinking from what she thought was a bottle of water. Unfortunately, the bottle had been used as a handy container for a highly toxic cleaning fluid by a member of the cleaning staff. Result was a very painful death for the lady who only wanted a refreshing swig of water.
It could happen to anyone; and it nearly did happen to me. I still can recall the taste as a tiny sip of what was supposed to be hot coffee reached my lips and tongue.
