Maybe the ice in the drinks .....maybe that or its aids ...the bad kind
My missus was amazed, when after a day of being very careful with what she ate and drank over in foreignorland, got ill after consuming several milky cocktails with ice in them.
You haven't seen 'ill' until you've seen african milk based cocktail with ice ill.
Oh yes, very similar happened to a couple in our group when we went to Morocco.
Awful scenes
