you won't starve, it's okay.

So, what would you do if you went out with your non-Muslim friends and they went to eat at a non-halal restaurant? Just order and eat, if you're non-Muslim like them. But if not, obviously, you shouldn't. You might wanna tell them you're full since you just had your meal, so ordering a drink would be enough. But make sure the drink is order-able (??), well, for Muslims. Then, because you would probably be starved by the time your movie is starting, I suggest you buy a stack of food before going into the cinema. Hot dog, large popcorn combo, potato wedges, snacks, anything. It's dark inside. Eat like crazy. No one's watching, I guarantee.
