Mezonos on Pita???

During conversation, an interesting tidbit about a friend came up. Their family minhag is *not* to wash for pita. They do wash for a laffa, and in Israel they wash for pita. But not in America. I found this to be a very strange minhag. It looks like bread and tastes like bread. Granted, it doesn't occupy the centerpiece of the meal. In falafel its used to hold everything together. Sort of like a wrap on a sandwich (which this friend likened to a cracker that doesn't need to be washed for).
Strange to me. What do you all think?
