True stories:
1. In my early 20's i, together with one Bosnian friend of mine, a muslim (who drinks a lot

), went to Montenegro as guests of another friend of ours.
For God knows what reason, his mother prepared a meal which had pork in it. We ate it and only after we ate it the Bosnian friend asked what was it that we were eating. He felt sick when he heard that it had pork. But really sick. Wanted to throw up and went to the WC (maybe he threw up there, i don't know).
So the second day for lunch we head sea food and it was nice and all, but after we ate it my Bosnian friend tells my Montenegrin friend: "Could you ask your mother to prepare something special for lunch tomorrow, but without telling me what is it".
Yes, we had pork the third day again and there were no problems at all.
2. When i was in Macedonia one Albanian ate pork but he was told that he's eating ostrich meat. After the lunch he even complemented the cook. I don't know if he ever found out what he was eating.
I know other Bosnians who have no problem eating pork (My father told me that back in Yugoslavia, when he was in the army, most of the Bosnian muslims had no problem eating pork, but they were hidding from eachother when doing it).
In the other Muslim country where i've been more often, Turkey, i haven't seen anyone eat pork though.
