I was having my McDonald 100% halal potato slice the other day which I had no idea why it was labelled that way when it struck me. Why do restaurants put a percentage to begin with? I mean is there such a thing as 50% halal or 25% halal to assure the consumer it’s 100%? It is either halal or haraam, there are no percentages whatsoever. I think the percentage is there as a marketing strategy.
