My wife and I with another couple were in Ottawa , eating in a great pizza place. Seated in the next booth was a Muslim family , dad and 3 kids, , the mother dressed in a burka. She picked up a piece of pizza, then somewhere, just above her waist , flipped open her burka and in and then up went the pizza. She ate it with the burka in place . Three pieces of pizza , then she used a napkin to clean up under there.
We laughed about it later but at the time , everyone else stopped eating to watch.
The zippered burka mouth fly has yet to be invented.
