If most of the F&B went halal, MUIS will be richer than the Catholic church and City Harvest just by collecting halal fees. I suspect that's the main reason why in the past 10 years, MUIS has been quietly supportive of fanatical preachers who urge muslims to take halal certs more seriously. It ultimately means more money for MUIS and a huge ego boost to collect a modified form of jizya from the kafirs in the form of halal license fees.
I no problem. No popcorns also no problem. Btw, nobody forcing them to sell food to Muslims. Just like SubWay. They can still sell with pork. We can live without patronising Subway.
