Turkey is a very popular place for the UK traveller to visit for holidays and you would expect food to be prepared in the traditional way without question the same as in Morrocco, Tunisia and Egypt. I can't imagine every single traveller is going to think about how the food was prepared come lunchtime. As for the non-Halal countries there is no guarantee that they are going to be any more humane. Spain has little regard for the suffering of bulls for sport let alone anything else. As long as an establishment has a notice to inform what is Halal and what is not I can't see a problem I suppose it could be set out far apart from non-Halal instead of next to or in a completely different area for somewhere like Tesco like they do in a Turkish food store. I don't like the thought of suffering either but even if I stick to veggie meals and vegetarian cheeses it isn't going to make a difference to the practises of how animals are treated it's only going to make me sleep better at night. Not so long ago there was footage of workers in a well known turkey farm in UK being captured on film using turkeys as cricket bats by swinging them by their necks causing a great deal of suffering to the poor things so you can't always guarantee cruelty free meat production.
