I’d go through the line with a bottle of whiskey and a side of bacon, again, and again, and again.
Here is what you do:
Select only muslim approved products. Then, wait until a large female infidel with a full cart has unloaded at the muslim line. Get behind her, & casually point out to Fatima the checker that a certain product or products MIGHT have pork or alcohol in them. You know, something like, “Wow. I really like the bacon they added to that soup”, or “I know a guy who claims he gets drunk on vanilla extract.”
Once you see the checker start to go on jihad, stand way back, look innocent, & watch the fun. Extra points if you film it & post link here.
(If you have to defend yourself, shout “Allah Akbar” several times.)
