Chawerma with fries

I went for a standard meal, Chawerma, in Tripoli, Tunnisia, and Algeirs. Well I guess in every country it tastes different. I figure I got acquainted to the taste in Egypt and in Canada, which were very similar mind you. However, When has fries been a major part of the sandwich. Fries seem to creep INSIDE the sandwich in Libya, evolve more in Tunisia and become a major component in Algeria. I am wondering would I ask for Chawerma in Morocco and get a sandwich of fries and some chawerma as a side order. I will have to wait on that one.
