While visiting Dubai, we noticed there is a pork shop in every supermarket with a sign "for non-muslims". In fact once we walked right into the shop without noticing the sign because it was in the corner and small. I know that the authorities in Dubai, or in the UAE in general, caters these foods as well as liquor for the expatriates who account for the majority of its population and that would probably make life easier for them being away from home. On the other hand, people coming to work in a muslim country should abide by the rules and regulations of this country. They have to be prepared to live without certain luxuries they used to have at home in sacrifice for having a well-paid job.
What concerns me about restaurants serving these foods & drinks is the possibility of using the same utensils for preparing, cooking, or serving these food & drink items and preparing our food. So the best thing to do is avoid eating in such restaurants altogether.
